<title>Introduction</title>
<p>At present, Chinese society has entered the era of aging population, with the aging process of the population aggravated and accelerated, more and more women into the perimenopausal period. Perimenopausal period refers to the period from the onset of endocrine, biological, and clinical features associated with menopause near menopause to within 1 year of menopause (<xref ref-type="bibr" rid="B1">1</xref>). During this period, due to the decline of ovarian function, the level of estrogen progesterone decreases in a cliff-like manner, the number and quality of oocytes decrease, and the levels of estrogen and progesterone continuously decline (<xref ref-type="bibr" rid="B2">2</xref>). Some women in this period may not only be prone to menstrual disorders, hot flashes, sweating, insomnia, palpitations, vertigo, fatigue, headache, frequent urination, and muscle aches throughout the body, pain and discomfort in the bone and joint parts of the body, emotional instability and other physiological symptoms, but also easily associated with anxiety, depression and other mental disorders (<xref ref-type="bibr" rid="B3">3</xref>). Foreign studies have shown that after women enter perimenopausal period, the risk of anxiety and depression is significantly higher (<xref ref-type="bibr" rid="B4">4</xref>), psychological distress and mood disorders significantly affect the physical health and quality of life of perimenopausal women (<xref ref-type="bibr" rid="B5">5</xref>). Previous treatments for mood disorders in perimenopausal women have mostly been menopausal hormone therapy and drug therapy (<xref ref-type="bibr" rid="B6">6</xref>), but hormone and drug therapy have many contraindications, and long-term use of drugs can also produce many adverse reactions (<xref ref-type="bibr" rid="B7">7</xref>). In addition to hormone and drug therapy, there are also studies on intervention through psychological care, and the method of intervention is mainly health education or through talking to patients, using external interventions such as language, attitude, expression, and behavior to affect the patient&#x2019;s understanding and mood. However, these methods also have certain defects, for example, there are no specific operating specifications, reproducibility is not strong, and the therapeutic effect cannot be ensured. Physical exercise has been recognized as a psychotherapeutic approach as a low-cost, complication-free, non-invasive non-pharmacological therapy (<xref ref-type="bibr" rid="B8">8</xref>). According to a survey in the United States, 80% of 1,750 psychologists believe that physical exercise is one of the effective treatments for depression, and 60% believe that physical exercise should be used as a treatment to eliminate anxiety (<xref ref-type="bibr" rid="B9">9</xref>). Among college students, many suffer from anxiety and depression due to learning and other setbacks, which can be slowed or eliminated by physical exercise (<xref ref-type="bibr" rid="B10">10</xref>). It has also been confirmed that moderate exercise has a significant anti-insomnia effect and has a positive regulatory effect on the sleep-wake cycle, which can replace sedative hypnotic drugs to a certain extent without side effects. Moreover, exercise training improves quality of life and mood while relieving sleep disturbances (<xref ref-type="bibr" rid="B11">11</xref>). It has been suggested that physical exercise may help to avoid them before mental health problems begin (<xref ref-type="bibr" rid="B12">12</xref>). It has also been shown that exercise improves symptoms in many existing psychiatric disorders (<xref ref-type="bibr" rid="B13">13</xref>).</p>
<p>Aerobics is an emerging sports program that integrates gymnastics, dance, music, is based on aerobic exercises, and is characterized by health, strength, and beauty (<xref ref-type="bibr" rid="B14">14</xref>, <xref ref-type="bibr" rid="B15">15</xref>). Existing research suggests that women&#x2019;s participation in mass aerobics can not only maintain positive and optimistic mood and improve mood, but also interfere with depression and anxiety. Beautiful and cheerful music rhythm and lively and pleasant physical movements can maximize people&#x2019;s enthusiasm and vitality, so that the tired mind can be effectively relaxed and the body and mind can be fully regulated (<xref ref-type="bibr" rid="B16">16</xref>, <xref ref-type="bibr" rid="B17">17</xref>). However, there is no research report on the effect of aerobics training on anxiety, depression and sleep quality in perimenopausal women. In this study, 8-week aerobics training was used to intervene perimenopausal women with anxiety, depression and insomnia to explore the effect of aerobics training in the treatment of mood disorders in perimenopausal women. It is expected to establish a psychological intervention method that can effectively alleviate the adverse emotions of perimenopausal women, is easy to operate, and is convenient for promotion.</p>

<title>Study subjects</title>
<p>In April 2022, using simple random sampling, total of 2,076 women aged 45&#x2013;55 years old in Chengdong Community, Fengshan Ecological Park Community and Bayi Community of Lianhuachi Street in Binhe Street, Lishi District, Luliang City were investigated by perimenopausal symptoms questionnaire. After the respondents signed the informed consent, the investigators used structured questionnaires to investigate the respondents. The questionnaire was designed with the question form method. To ensure the quality of the questionnaire, the questionnaire was filled out with detailed instructions and explanations from the investigators before filling in the questionnaire. After the informed consent of the respondents, the concerns of privacy disclosure and other aspects were eliminated, and the active cooperation of the respondents was obtained. For those with low education level who could not complete the questionnaire independently, the investigators read each item and the respondents checked the corresponding options after thinking independently. After the completion of the return are reviewed, the missing items face to face explanation and ask to fill back. A total of 974 women with anxiety, 839 women with depression and 1,505 women with insomnia (including the coexistence of three symptoms) were screened. According to the inclusion and exclusion criteria, 289 participants were finally identified, including 39 participants with anxiety only, 43 participants with depression only, 51 participants with insomnia only, 38 participants with anxiety and depression, 42 participants with anxiety and insomnia, 52 participants with depression and insomnia, and 24 participants with anxiety and depression and insomnia. The total number of patients with anxiety was 143, with an average age of 51.4 &#x00B1; 4.7 years; the total number of patients with depression was 157, with an average age of 51.7 &#x00B1; 4.3 years; and the total number of patients with insomnia was 169, with an average age of 52.2 &#x00B1; 4.6 years. There was no significant difference between the ages of each group (<italic>F</italic> = 1.25, <italic>P</italic> = 0.29). Inclusion criteria: (1) Perimenopausal symptoms (menstrual disorders, vertigo, palpitations, headache, tinnitus, facial flushing, anxiety, depression, insomnia, etc.) in the past 6 months, in line with perimenopausal diagnosis.

<title>Self-rating anxiety scale</title>
<p>The (<xref ref-type="bibr" rid="B19">19</xref>) was developed by Zung to assess the severity of an individual&#x2019;s anxiety state over the past week. SAS is a simple clinical tool for analyzing subjective anxiety sensation in patients and is suitable for adults with anxiety symptoms, with the advantages of high effectiveness, simple method, and easy analysis. The scale consists of 20 items, with a 4-level score, 1 indicating &#x201C;no or little time&#x201D; and 4 indicating &#x201C;most or all time.&#x201D; The scores of each item are additive, and SAS &#x2265;50 is considered anxiety, and the higher the score, the more severe the degree of anxiety. Cronbach&#x2019;s alpha coefficient for this inventory was 0.820 (<xref ref-type="bibr" rid="B20">20</xref>).</p>

<title>Self-rating depression scale</title>
<p>The subjective experience of the (<xref ref-type="bibr" rid="B19">19</xref>) was developed by Zung to assess individuals&#x2019; depressive mood over the past week. SDS is a commonly used self-assessment tool for depression at home and abroad, which is characterized by easy use, intuitive and relatively accurate reflection of the degree of depression subjectively felt by self-assessors, and is a clinical tool suitable for adults to measure subjective depression feelings. The scale consists of 20 items scored at 4 levels, with 1 indicating &#x201C;no or little time&#x201D; and 4 indicating &#x201C;most or all of the time.&#x201D; The scores of each item were additive, standard score = coarse score &#x00D7; 1.25, less than 53 points for no depression, 53&#x2013;62 points for mild depression, 63&#x2013;72 points for moderate depression, and more than 72 points for severe depression. The higher the score, the more severe the depression. Cronbach alpha coefficient for this inventory was 0.84 (<xref ref-type="bibr" rid="B20">20</xref>).</p>

<title>Pittsburgh Sleep Quality Index scale</title>
<p>The PSQI (<xref ref-type="bibr" rid="B21">21</xref>) is a scale developed by the University of Pittsburgh to evaluate sleep quality in the past 1 month. This scale is used to assess individual sleep quality and consists of 7 sleep scoring factors, each scored on a scale of 0&#x2013;3, and the cumulative PSQI total score range of each factor (0&#x2013;21), with higher scores indicating worse sleep quality. The total PSQI score was divided into four levels: 0&#x2013;5 points for good sleep quality, 6&#x2013;10 points for better sleep quality, 11&#x2013;15 points for fair sleep quality, and 16&#x2013;21 points for very poor sleep quality.</p>

<p>This study showed that all perimenopausal women who volunteered to participate in the study were able to adhere to 16 aerobics training sessions over 8 weeks with good compliance, which may be related to the frequent occurrence of anxiety, depression and sleep disorders in the perimenopausal period without good intervention, or to the health care, medical treatment, fitness, bodybuilding, and interest and non-impairment unique to aerobics training. After the intervention, the symptoms of anxiety, depression and sleep disorder were improved to some extent, 83.22% of anxiety symptoms, 84.08% of depression symptoms and 89.94% of sleep disorders were relieved, indicating that aerobics training has a significant effect on improving the symptoms of psychological disorders in perimenopausal women. Aerobics training can be used as a safe and easy to operate training method to improve anxiety, depression and sleep problems in perimenopausal women.</p>
<sec id="S4.SS1">
<title>Anxiety, depression and sleep quality in perimenopausal women</title>
<p>Perimenopause represents a delicate transitional period of female life during which physical, emotional, psychological, and social changes mark the progression of women from fertile life to climaterium or reproductive loss, withwide sexual fluctuations until the onset of hypergonadotropic hypogonorrhea (<xref ref-type="bibr" rid="B22">22</xref>). It is generally 45&#x2013;55 years of age and is an important stage in the transition of women from middle to old age. Although neuroendocrine changes during the menopausal transition are varied and complex, the central biological event during this period is gradual ovarian failure, both in the number of follicles and in the quality of oocytes. Because ovarian function gradually deteriorates, causing dysfunction of the hypothalamic-pituitary-ovarian endocrine axis and decreased estrogen levels, about two-thirds of women experience varying degrees of perimenopausal symptoms (<xref ref-type="bibr" rid="B23">23</xref>&#x2013;<xref ref-type="bibr" rid="B25">25</xref>). For example, autonomic dysfunction symptoms (palpitations, vertigo, headache, insomnia, tinnitus; skin paresthesia, etc.) (<xref ref-type="bibr" rid="B26">26</xref>&#x2013;<xref ref-type="bibr" rid="B28">28</xref>) and psycho-psychological symptoms (irritability, anxiety, depressed mood; memory loss, cognitive decline; depression, inability to self-control mood, etc.) (<xref ref-type="bibr" rid="B29">29</xref>&#x2013;<xref ref-type="bibr" rid="B31">31</xref>) as well as cardiovascular system symptoms (menopausal pseudo angina symptoms such as palpitations, chest tightness, precordial discomfort; menopausal hypertension due to emotional instability, poor sleep, dysphoria, etc.) (<xref ref-type="bibr" rid="B32">32</xref>&#x2013;<xref ref-type="bibr" rid="B35">35</xref>) directly affect women&#x2019;s physical and mental health and well-being. Investigations have shown that adult females have 41% higher insomnia rates than males (<xref ref-type="bibr" rid="B36">36</xref>). Before puberty, there is no male-to-female difference in the prevalence of insomnia, but with menstruation, the rate of insomnia increases dramatically in women, 2.5 times that in men (<xref ref-type="bibr" rid="B37">37</xref>). Before and after natural menopause, the incidence of insomnia disorder in women increased significantly compared with that before menopause. According to the National Women&#x2019;s Health Study (SWAN), the prevalence of sleep disorders increases with age. The prevalence of sleep disorders varies from 16 to 42% in premenopausal women, 39 to 47% in perimenopausal women, and 35 to 60% in postmenopausal women (<xref ref-type="bibr" rid="B38">38</xref>). Lee et al. (<xref ref-type="bibr" rid="B39">39</xref>) stated that perimenopausal sleep problems are distinct from other causes of sleep disorders and are mainly characterized by: difficulty falling asleep, frequent awakenings at night, early morning awakenings, and inability to sleep after awakening. In addition to sleep disorders, women entering the perimenopausal period experience a range of neuropsychiatric changes due to alterations and dysregulation of the body&#x2019;s associated endocrine function, causing psychological dysfunction, mainly manifested as depression and anxiety, and often both symptoms coexist (<xref ref-type="bibr" rid="B40">40</xref>). A survey of epidemiology in China showed that perimenopausal women experienced anxiety in 81.58%, mild to moderate anxiety in 68.42%, depression in 85.09%, and mild to moderate depression in 73.68% (<xref ref-type="bibr" rid="B41">41</xref>). Mehrnoush et al. (<xref ref-type="bibr" rid="B42">42</xref>) showed that menopause is not a high-risk period for mental illness but causes psychological problems, the most common of which are anxiety and depression, which impair their ability to cope with events in daily life and work, and reduce the quality of life of women. Herson et al. (<xref ref-type="bibr" rid="B43">43</xref>) have shown that women not only have an increased risk of depression and anxiety during the perimenopausal and menopausal transition (MT) periods, but also experience higher severity of depressive symptoms during the perimenopausal period compared with before and after menopause. The latest Australian mental health data show that mental illness is more prevalent in women than in men, and that women who develop major depression are twice as likely as men (<xref ref-type="bibr" rid="B44">44</xref>). However, recurrent endocrinological changes before and after menopause may be responsible for the higher risk of depression from adolescence to old age in women than in men (<xref ref-type="bibr" rid="B45">45</xref>). The term anxiety is commonly used to describe a wide variety of symptoms and may include features of various anxiety disorders, such as panic disorder (e.g., sudden feelings of unexplained fear) or generalized anxiety (e.g., excessive and uncontrollable worry, irritability), or physical symptoms, such as shortness of breath and rapid heartbeat. Relatively few studies have been conducted on the relationship between anxiety and menopause (<xref ref-type="bibr" rid="B46">46</xref>). However, studies have shown that the menopausal transition is a time of increased risk for the onset or worsening of anxiety symptoms (<xref ref-type="bibr" rid="B47">47</xref>), and studies have also demonstrated a significant increase in anxiety symptoms in the perimenopausal period (<xref ref-type="bibr" rid="B48">48</xref>).</p>

<sec id="S4.SS2">
<title>Effect of exercise on anxiety, depression and sleep quality in perimenopausal women</title>
<p>Exercise, as a low-cost, uncomplicated, and non-invasive non-pharmacologic therapy, not only helps prevent and improve many health problems, such as lowering blood pressure, enhancing cardiovascular fitness, losing weight, and preventing chronic diseases, such as cancer, diabetes, hypertension, obesity, osteoporosis, musculoskeletal pain, and neurodegenerative diseases (Parkinson&#x2019;s disease, Alzheimer&#x2019;s disease, and amyotrophic lateral sclerosis, etc.) (<xref ref-type="bibr" rid="B49">49</xref>, <xref ref-type="bibr" rid="B50">50</xref>), but also helps improve mental disorders (such as anxiety and depression) and reduce the risk of morbidity (<xref ref-type="bibr" rid="B51">51</xref>). In otherwords, exercise promoteswell-being and enhancing mood. Studies have shown that working out and other forms of physical activity have irreplaceable promoting effects on human physical and mental health (<xref ref-type="bibr" rid="B52">52</xref>).</p>
<p>Studies have shown that the use of exercise to treat major depression has been recommended in some clinical guidelines (<xref ref-type="bibr" rid="B53">53</xref>), suggesting that exercise improves overall health, including depressive symptoms inwomen in their middle-aged and olderyears, according to a recent meta-analysis (<xref ref-type="bibr" rid="B54">54</xref>). Similar findings were obtained by Roh (<xref ref-type="bibr" rid="B55">55</xref>), where a 16-week Pilates exercise program resulted in significant relief of depressive symptoms in older women. For anxiety, adults over the age of 50 with high levels of physical activity report lower levels of anxiety symptoms and status (<xref ref-type="bibr" rid="B56">56</xref>). In a recently published meta-analysis, itwas found that programmed exercise, at a low-to-moderate intensity for at least sixweeks, seems to improve symptoms of mild to moderate anxiety in middle-aged and elderlywomen (<xref ref-type="bibr" rid="B57">57</xref>). In addition, Li et al. (<xref ref-type="bibr" rid="B58">58</xref>) showed that a 3-month fitness running exercise intervention (3 times/week, 50&#x2013;70% maximum heart rate) resulted in a significant improvement in depression in depressed women, as shown by a significant decrease in depression handsome selection scale scores, self-rating depression scale scores, and depression 90-item symptom checklist scores. A study by Tiller (<xref ref-type="bibr" rid="B59">59</xref>) of Australian women showed that women who were less than the recommended 2.5 h of moderate exercise per week continued to experience higher rates of anxiety and depression. Aibar-Almaz&#x00E1;n et al. (<xref ref-type="bibr" rid="B60">60</xref>) analyzed the effects of Pilates based exercise program on sleep quality, anxiety, depression, and fatigue in postmenopausal women aged 60 years and older living in Spanish communities, and showed that 12-week Pilates exercise intervention had beneficial effects on their sleep quality, anxiety, depression, and fatigue. Specifically, all Pittsburgh Sleep Quality Index (PSQI) domains aswell as in the PSQI total score were significantly improved, and Hospital Anxiety and Depression Scale (HADS) score and fatigue severity scale were significantly reduced. Poor sleep quality is strongly associated with a low level of physical activity among postmenopausalwomen (<xref ref-type="bibr" rid="B61">61</xref>). Cai et al. (<xref ref-type="bibr" rid="B62">62</xref>) study showed,traditional exercise training programs, such as aerobics, it has been shown to positively affect on sleep quality in postmenopausal women, presented as10-week moderate- to high-intensity step aerobics training program (40&#x2013;45 min/times, 3 times/week, 10 weeks, intensity of 75&#x2013;85% of the heart rate reserve)can enhance the quality of sleep and increase the melatonin levels in sleep-impaired postmenopausal women, and a systematic review and meta-analysis of randomized controlled trial concluded that programmed exercise enhance sleep quality among middle-aged women (<xref ref-type="bibr" rid="B63">63</xref>). Tadayon et al. (<xref ref-type="bibr" rid="B64">64</xref>) also found improvements in both the Pittsburgh Sleep Quality Index total score and domains among postmenopausal women after twelve weeks of pedometer-based walking. Newton et al. (<xref ref-type="bibr" rid="B65">65</xref>) randomized controlled studies performed showed that, postmenopausal women with insomnia were randomly assigned to either yoga classes, exercise at home, or their usual activity. They found that, compared to usual activity, women assigned to yoga saw improvements in their sleep quality and sleep disorders, both domains of Pittsburgh Sleep Quality Index. Buchanan et al. (<xref ref-type="bibr" rid="B66">66</xref>) studie showed that, 12 weeks of yoga or aerobic exercise can makelate transition and postmenopausal women aged 40&#x2013;62 years with hot flashes Significant improvement in sleep stability, mean total sleep time markedly increased,mean wake after sleep onsetmarkedly decreased, mean coefficient of variationfor number of long awakenings &#x003E;5 min markedly decreased. Curi et al. (<xref ref-type="bibr" rid="B67">67</xref>) reported improvements in Pittsburgh Sleep Quality Index total score, use of sleeping medication, and sleep latency after 16 weeks of intervention with Pilates exercises in women aged 60 years and over. Gulia and Sreedharan (<xref ref-type="bibr" rid="B50">50</xref>) confirmed the research on post menopausal subject, after administering the 24 weeks of yoga-nidra practice and exercise module protocol, there was remarkable elevation in mood both on waking up and entire day from 5th week onward. Mood shifted toward a happier state. Latency to sleep decreased after 4 weeks, while total sleep time improved only after 16 weeks of dual management strategy.</p>

<title>Effect of aerobics training on anxiety, depression and sleep quality in perimenopausal women</title>
<p>As an aerobic exercise, aerobics with its enthusiasm, rhythm, movement stretch, beautiful and powerful, giving people booming, spiritual quality, free driving force, so that exercisers and ornaments can feel the beautiful realm of the combination of aerobics and beauty. It is very rich in physical exercise and mental health care value, with popularity, the characteristics of the whole people, suitable for the diverse needs of Chinese public fitness, but also an important part of the national fitness exercise. Completing a set of aerobics is equivalent to doing a thorough whole body movement. Aerobics can improve and improve the motor function of muscle fibrous tissue, joint tissue and bone. Mass aerobics can also be flexibly arranged for different objects, different purposes of exercisers (such as weight loss, strong waist, body, etc.). For example: middle-aged and elderly aerobics, adolescent aerobics, young children aerobics, pregnant women aerobics, warm-up aerobics, body aerobics, rhythm aerobics, weight loss aerobics, free-hand aerobics, device aerobics, body parts aerobics and so on. Moreover, mass aerobics strictly follow the physiological law of sports load from small to large, movement from simple to complex; intensity from weak to strong, gradually increase load, and gradually decrease when reaching and maintaining a certain negative. In short, mass aerobics can enhance physical fitness, improve body shape, change mental outlook and temperament, purify the mind, give people beauty edification. According to the researchers, women participating in mass aerobics can not only maintain a positive and optimistic emotional state and improve mood, but also have a certain intervention effect on depression and anxiety. Beautiful and cheerful music rhythm, lively and happy body movements can maximize the enthusiasm and vitality of people, so that the tired mind can be effectively relaxed, physical and mental regulation. For women who concentrate on exercise, under the guidance of professional coaches, they can not only get systematic fitness exercise, enhance self-confidence, but also enhance sense of honor and collectivism, which helps to establish a good interpersonal relationship. In this study, after 8 weeks of aerobics training, the anxiety, depression and sleep status of perimenopausal women were significantly improved, indicating that aerobics training can be used as a relatively safe and easy to operate training method to improve the anxiety, depression and sleep problems of perimenopausal women. The results of this study also showed that those who had only one symptom of anxiety, depression and insomnia before the intervention, all symptoms were significantly relieved after the intervention. The remission rate was more than 80% when the two symptoms existed before intervention. Even those with the three symptoms at the same time had a remission rate of over 65 percent. It indicates that even if the symptoms are more complicated and the disease is more serious, the 8-week aerobics training can also significantly alleviate. According to the frequency of self-practice after class, it was found that the more the number of self-practice of aerobics training, the lower the SAS score, SDS score and PSQI score, indicating that the number of training, frequency and amount of training can affect the intervention effect. Further statistics showed that anxiety was relieved by 98.25%, depression was relieved by 98.31%, and sleep disorder was relieved by 100% for those who exercised by themselves more than 3 times a week. The remission rates of anxiety, depression and sleep disorders were 77.55, 86.54, and 92.98% for those who practiced by themselves 1&#x2013;2 times a week. However, the relief rates of the three symptoms were 67.57, 60.87, and 71.74% for those who only relied on collective training and did not exercise by themselves, showing significant differences between the groups, indicating that even short-term concentrated calisaerobics training can also play a positive role in alleviating anxiety and depression symptoms and improving sleep.</p>

<title>Summary</title>
<p>Aerobics training can effectively improve the anxiety and depression of perimenopausal women, improve the quality of sleep, and can be used as a predictive method to improve the mental health level of perimenopausal women. This method requires simple conditions, can use group counseling, can also be independent practice, is an effective psychological intervention means, suitable for clinical promotion.</p>
<p>Mental health intervention for perimenopausal women is a long process. Although this study found that the SAS score, SDS score and PSQI score of perimenopausal women were improved to a certain extent after 8 weeks of intervention, further continuous intervention and follow-up verification are needed to systematically evaluate the long-term efficacy of aerobics training intervention. In addition, the sample size included in this study was not large enough, and subsequent work needs to expand the sample size to verify these conclusions. And when it comes to why exercise can improve mood and mental health, These include the endorphin hypothesis, the thermogenic hypothesis, mitochondrial dysfunction, mammalian target of rapamycin (mTOR), neurotransmitter dysfunction and the hypothalamic pituitary-adrenal (HPA) axis, All of which have been proposed to play a mechanistic role in altered mental states. Further studies are needed in the future to investigate the physiological and biochemical molecular mechanisms by which exercise improves depression, anxiety, and sleep disorders in perimenopausal women.</p>
