To investigate the association between weight status and sexual activity in middle-aged and older adults.
Cross-sectional analysis on Wave 6 (2012/13) of the English Longitudinal Study of Ageing. Data were from 2,200 men and 2,737 women aged ≥50 years (mean 68.2 years). The explanatory variable was weight status, defined as normal-weight (BMI: ≤24.9), overweight (BMI: 25.0-29.9) or obese (BMI: ≥30) based on objective measurements of height and weight. Outcome variables were any self-reported sexual activity in the last year (yes/no) and, if yes, frequency of sexual intercourse in the last month. Covariates included a range of sociodemographic, lifestyle, and health-related variables. Associations were analysed using binary (past-year sexual activity) and ordinal (frequency of past-month sexual intercourse) logistic regression models.
The majority (73.3%) of men and half (50.0%) of women reported any sexual activity in the last year. The odds of reporting any sexual activity in the last year did not differ significantly by weight status in either men or women. However, among those who were sexually active, men with overweight (OR = 1.45, 95% CI 1.15-1.81, p = 0.002) or obesity (OR = 1.38, 95% CI 1.07-1.77, p = 0.015), and women with overweight (OR = 1.34, 95% CI 1.05-1.71, p = 0.017) reported significantly more frequent sexual intercourse in the last month compared with those who had a BMI in the normal-weight range, after adjustment for covariates.
Older adults with overweight or obesity who are sexually active engage in more frequent sexual activity than those who are normal weight.
探讨中老年人群体的体重状况与性行为之间的关联。
利用英国老龄化纵向研究第 6 波(2012/13 年)的横断面分析数据。数据来源于 2200 名年龄在 50 岁及以上的男性(平均年龄 68.2 岁)和 2737 名女性。解释变量为体重状况,根据身高和体重的客观测量值定义为正常体重(BMI:≤24.9)、超重(BMI:25.0-29.9)或肥胖(BMI:≥30)。因变量为过去一年中任何形式的自我报告性行为(是/否),以及如果有,过去一个月中性交的频率。协变量包括一系列社会人口学、生活方式和与健康相关的变量。采用二项(过去一年的性行为)和有序(过去一个月的性交频率)逻辑回归模型分析相关性。
大多数(73.3%)男性和半数(50.0%)女性报告过去一年中有任何性行为。男性和女性的体重状况与过去一年报告性行为的可能性均无显著差异。然而,在有性行为的人群中,超重的男性(OR=1.45,95%CI 1.15-1.81,p=0.002)或肥胖的男性(OR=1.38,95%CI 1.07-1.77,p=0.015),以及超重的女性(OR=1.34,95%CI 1.05-1.71,p=0.017)与 BMI 处于正常范围内的人相比,过去一个月的性行为更为频繁,经协变量调整后。
活跃的超重或肥胖的老年成年人比体重正常的人有更频繁的性行为。
