ImportanceNumerous studies have documented the association of self-rated health (SRH) with chronic diseases. However, few studies have investigated its association with semen quality.ObjectiveTo examine the association of SRH with semen quality among men undergoing assisted reproductive technology (ART) in China.Design, Setting, and ParticipantsThis cross-sectional study recruited male partners in couples undergoing ART treatment at the Center for Reproductive Medicine, Tongji Hospital, Wuhan, China. A total of 1262 men underwent 2 semen examinations and completed a questionnaire on SRH between December 2018 and January 2020. Data analysis was performed from November 20, 2022, to March 24, 2023.ExposureSRH, including overall physical and mental health, as well as reproductive-related physical and mental health specifically, were reported at baseline recruitment.Main Outcomes and MeasuresSperm concentration, sperm progressive motility, sperm motility, and sperm count as semen quality parameters.ResultsThe study included 1262 men with a mean (SD) age of 32.79 (5.25) years and body mass index of 24.37 (3.68). Men with poorer SRH had lower semen quality (eg, sperm concentration among poor vs very good overall physical health: percentage variation, −14.67%; 95% CI, −23.62% to −4.66%). Among 4 components of SRH, a greater reduction in semen quality was estimated for reproductive-related SRH compared with overall SRH, whereas the greatest reduction was observed for reproductive-related physical SRH. In comparison with men with very good reproductive-related physical SRH, men with poor reproductive-related physical SRH had differences of −24.78% (95% CI, −32.71% to −15.93%) and −25.61% (95% CI, −33.95% to −16.22%) in sperm count and concentration, respectively, and regression coefficients of −9.38 (95% CI, −12.01 to −6.76) and −9.24 (95% CI, −11.82 to −6.66) for sperm motility and sperm progressive motility, respectively.Conclusions and RelevanceIn this cross-sectional study of Chinese men, poorer SRH was associated with lower semen quality, and reproductive-related physical SRH was the most pronounced indicator. Our findings suggest that SRH, especially reproductive-related physical SRH, was a good indicator of semen quality, which should inform public and clinical regulatory decisions.

“…As a result, the associations of PA and SB with SRH may differ by country. However, research investigating these associations among adolescents in China is limited [21,44]. No studies have examined the associations of PA and SB with SRH among children and adolescents in China.…”

Objective The study aimed to analyze the independent and joint associations of physical activity (PA) and sedentary behavior (SB) with self-rated health (SRH) among Chinese children and adolescents. Methods Cross-sectional data on moderate-to-vigorous physical activity (MVPA), school-based PA, extracurricular physical activity (EPA), screen time (ST), homework time, and SRH were assessed through a self-report questionnaire in the sample of 4227 Chinese children and adolescents aged 13.04 ± 2.62 years. Binary logistic regression was used to compare gender differences in PA, SB, and SRH among children and adolescents, and analyses were adjusted for age and ethnicity. Results In independent associations, boys and girls engaging in ≥60 min/day of MVPA and >1 hour/day of EPA reported optimal SRH. Only boys who participated in >1 hour/day of school-based PA were significantly more likely to have optimal SRH (OR = 1.49, 95%CI = 1.19–1.86). Only girls who had ≤2 hours/day of ST were significantly associated with optimal SRH (weekdays: OR = 1.38, 95%CI = 1.10–1.74; weekends: OR = 1.40, 95%CI = 1.14–1.71; whole week: OR = 1.42, 95%CI = 1.16–1.73). In joint associations, regardless of SB recommendation, meeting PA recommendation was significantly associated with optimal SRH in both boys (meet PA and SB recommendations, OR = 1.61, 95%CI = 1.03–2.50; meet PA but not SB recommendations, OR = 2.40, 95%CI = 1.57–3.65) and girls (meet PA and SB recommendations, OR = 3.72, 95%CI = 2.08–6.65; meet PA but not SB recommendation, OR = 4.27, 95%CI = 2.09–8.75). Conclusion Increased PA and reduced SB were positively associated with optimal SRH in Chinese children and adolescents. Notably, lower ST positively influenced only girls’ SRH. Meeting PA recommendation is more impactful than meeting SB recommendation for improving SRH in Chinese children and adolescents. Future studies could explore these associations using objective measures of PA and SB in China.
