Aims: Evidence concerning the impact of ambient particulate matter (PM) on mental health is just emerging and inconsistent. Air pollution with high PM levels has been frequently reported in China, however, no Chinese study has determined the association between PM exposures and anxiety hospitalizations. We examined the potential association between PM concentrations and anxiety admissions in 26 Chinese cities from January 2014 to December 2015.Methods: A time-stratified case-crossover design was employed in the study. Anxiety hospitalizations were identified according to ICD-10 from the electronic hospitalization summary reports system in China. Conditional logistic regression was applied to estimate the relation between PM levels and anxiety admissions, stratified by age and sex.Results: Positive associations between PM2.5/PM10 and admitted anxiety cases were observed. PM2.5 had the largest effect estimate at lag 5 days, with a per 10 μg/m3 increase corresponding to a 0.63% (95% CI, 0.26-1.00) increase in anxiety admissions. PM10's largest effect estimate was observed at lag 3 days, increasing 0.37% (95% CI, 0.12-0.62) anxiety admissions per 10 μg/m3. Females were more sensitive to PM2.5/PM10 concentrations than males, however, the effect modification by age was not significant. A marginally significant distinction in anxiety hospitalizations was found in patients with and without CVDs when they were exposed to PM2.5.Conclusions: Our findings indicate that short-term exposure to increased concentrations of PM2.5/PM10 exacerbates risks of anxiety hospitalizations in 26 Chinese cities. We observed effect modification by sex, with significantly stronger associations in female patients. This study offers the promise that reducing PM air pollution could probably reduce the huge disease burden from anxiety disorders. [ABSTRACT FROM AUTHOR]

Sexuality has an important impact on people's physical and mental health, but current research on the sexual activity of older Chinese women has many limitations and more detailed studies are needed. The objective was to determine the prevalence of sexual activity and related factors in women aged 55 to 85 years in Hunan, China. Based on the data from the Hunan Provincial Women Health Needs Survey in 2018, we conducted a secondary analysis of 2,401 older women aged 55 and above. The dependent variable was sexual activity, and independent variables included sociodemographic characteristics, health behaviors, reproductive and chronic medical history, and psychological characteristics. All statistical analyses were performed using SPSS 26.0. Chi-square test was used to assess the association between categorical variables, and binary logistic regression was used to examine factors related to sexual activity. Sexual activity and related factors. The prevalence of sexual activity among older women was 12.5% (301/2401) in the past month. Having a partner (OR = 1.484; 95% CI, 1.048-2.101; P =.026), jogging (OR = 2.061; 95% CI, 1.391-3.054; P <.001), dancing (OR = 1.477; 95% CI, 1.106-1.974; P =.008), vegetarian-based diet (OR = 2.197; 95% CI, 1.334-3.618; P =.002), meat-based diet (OR = 2.196; 95% CI, 1.144-4.216; P =.018) were positively associated with being sexually active. Whereas, aging (OR = 0.781; 95% CI, 0.647-0.942; P =.010), living in the urban (OR = 0.628; 95% CI, 0.488-0.808; P <.001), hypertension (OR = 0.702; 95% CI, 0.520-0.949; P =.021), and anxiety (OR = 0.680; 95% CI, 0.475-0.972; P =.034) were negatively associated with being sexually active. Health care workers need to be aware that older women still have sexual activity and understand the needs of older women for sex education, take the initiative to discuss safe sex with them, and solve their sexual problems. This is one of the largest studies to determine the prevalence of sexual activity among older women in China and its related factors. In addition, new factors such as exercise types and eating habits related to sexual activity were discovered. The limitation of this study is that it did not use a specific questionnaire to assess the sexual activity and did not consider physical tenderness other than sexual intercourse. Some older women still have had sexual activity in the past month and factors such as lifestyles that can be changed and chronic diseases that can be self-managed were found to predict sexual activity.

Background: Leisure time physical activity (LTPA) is beneficial for late-life depression (LLD). The main purpose of this study was to estimate the associations between LTPA parameters (intensity, duration, frequency) and LLD.Methods: Through the 2018 Women Health Needs Survey, data on 1,892 women aged 55-70 in Hunan, China, were studied. Depression was measured by the 9-item Patient Health Questionnaire (PHQ-9). Self-reported LTPA parameters were collected. Binary logistic regression models were used to compute odds ratios (OR) for LTPA for predicting depression. Sensitivity analyses were conducted to examine the effect of missing values.Results: Moderate LTPA volume (OR = 0.582, p = 0.027, 95% CI [0.360-0.941] for 150-299 min/week and OR = 0.392, p = 0.002, 95% CI [0.215-0.714] for ≥300 min/week) was associated with reduced depression, while vigorous LTPA could increase the risk (OR = 2.414, p = 0.029, 95% CI [1.095-5.325] for <75 min/week and OR = 3.824, p = 0.007, 95% CI [1.439-10.158] for ≥75 min/week). Frequent (6-7 days/week), moderate LTPA had a lower risk (OR = 0.570, p = 0.021, 95% CI [0.353-0.918]), while frequent (≥3 days/week), vigorous LTPA increased the risk (OR = 5.103, p = 0.001, 95% CI [1.977-13.172]). The adjusted relationship between the duration and depression was not observed. The results were supported by the sensitivity analysis based on missing value replacement.Limitations: In this cross-sectional study, LTPA data were self-reported and no data on light LTPA were collected.Conclusions: Moderate LTPA, associated with mental health benefits, should be recommended for older women instead of vigorous LTPA.
