Associations between masturbation frequency, anxiety, and sleep disturbances during the COVID-19 era.

Abstract

The COVID-19 pandemic has markedly influenced people's lifestyle and sexual behaviors, including masturbation patterns. This study delved into how masturbation frequency could impact anxiety levels, sleep quality, and somatic symptoms post-masturbation among Chinese adults during this period. From December 2022 to January 2023, we conducted a cross-sectional survey, gathering data via WenJuanXing, a leading online survey platform in China. This platform facilitated the recruitment of a diverse cohort, spanning various age groups and geographical locations. Masturbation frequency among participants was subjectively categorized into three levels: 'lesser' (a few times over the past year), 'moderate' (once to three times a month), and 'greater' (weekly to almost daily). To assess anxiety levels and sleep quality, we employed the Generalized Anxiety Disorder 7-item (GAD-7) scale and the Pittsburgh Sleep Quality Index (PSQI), respectively. Among 1500 participants, we received 1423 valid responses. Among these, 65% (n = 930) reported engaging in masturbation in the past year, of whom 87.5% reported subjectively experiencing various levels of fatigue post-masturbation. These 930 responses were subsequently analyzed in-depth (e.g., non-parametric test and pathway analysis), with ages ranging from 18 to 54 years (mean age = 30.5, SD = 7.42). Notably, our findings indicate that participants with greater masturbation frequency exhibited higher anxiety levels [GAD-7 median score: 6 (lesser) vs. 4 (moderate) vs. 8 (greater), p < 0.001, Cohen's f = 0.41] and poorer sleep quality [PSQI median score: 5 (lesser) vs. 4 (moderate) vs. 7 (greater), p < 0.001, Cohen's f = 0.46]. A rough positive correlation between masturbation frequency and PSQI score was also observed (β = 0.16, p < 0.001). These results suggest potential mental and sleep benefits at moderate frequencies, especially in contrast to greater frequencies. However, the cross-sectional design and subjective categorization of masturbation frequency in our study limit our ability to draw definitive causal conclusions. These limitations highlight the need for future longitudinal research employing more precise categorizations of masturbation behavior, such as frequency, to delve deeper into these relationships and understand their underlying mechanisms.
