The majority of adults in the United States fail to meet the Centers for Disease Control and Prevention (CDC) physical activity (PA) guideline recommendations for health promotion. Despite evidence of disparities by sexual orientation in adverse health outcomes related to PA, little is known about whether PA patterns and the likelihood of meeting these guidelines differ between heterosexual and sexual minority (SM) men and women.
In 2018, we pooled unweighted respondent data from Kaiser Permanente Northern California Member Health Surveys conducted in 2008, 2011, and 2014/15 (N=42,534) to compare PA patterns among heterosexual and SM men and women.
In total, 38.8% of heterosexual men, 43.4% of SM men, 32.9% of heterosexual women, and 40.0% of SM women meet the CDC PA guidelines, yet there was no statistically significant difference in the adjusted odds of meeting these guidelines. Compared with heterosexual women, SM women engage in PA more frequently [odds ratio=0.81; 95% confidence interval (CI), 0.74-0.89], for more minutes per week on average (12.71; 95% CI, 4.85-20.57), and at higher levels of intensity (relative risk ratio=1.26; 95% CI, 1.02-1.56). Compared with heterosexual men, SM men engage in PA more frequently (OR=0.85; 95% CI, 0.74-0.98), for fewer minutes per week on average (-12.89; 95% CI, -25.84 to 0.06), and at lower levels of intensity (relative risk ratio=0.83; 95% CI, 0.67-0.99).
We find that SMs get more frequent PA than their heterosexual peers, which suggests that the higher prevalence of obesity and other PA-related adverse health outcomes among SMs may be due to factors other than PA patterns.
大多数美国成年人无法达到疾病控制与预防中心（CDC）为促进健康而制定的身体活动（PA）指南建议。尽管有证据表明，在与 PA 相关的不良健康结果方面，性取向存在差异，但对于异性恋和性少数群体（SM）男性和女性的 PA 模式以及达到这些指南的可能性是否存在差异，知之甚少。
在 2018 年，我们合并了 Kaiser Permanente 北加州会员健康调查 2008 年、2011 年和 2014/15 年进行的未加权受访者数据（N=42534），以比较异性恋和 SM 男性和女性的 PA 模式。
总的来说，38.8%的异性恋男性、43.4%的 SM 男性、32.9%的异性恋女性和 40.0%的 SM 女性符合 CDC 的 PA 指南，但在符合这些指南的调整后几率上没有统计学意义上的差异。与异性恋女性相比，SM 女性更频繁地进行 PA [优势比=0.81；95%置信区间（CI），0.74-0.89]，平均每周进行的时间更长（12.71；95%CI，4.85-20.57），且强度更高（相对风险比=1.26；95%CI，1.02-1.56）。与异性恋男性相比，SM 男性更频繁地进行 PA（OR=0.85；95%CI，0.74-0.98），平均每周进行的时间更短（-12.89；95%CI，-25.84 至 0.06），且强度更低（相对风险比=0.83；95%CI，0.67-0.99）。
我们发现，SM 人群比他们的异性恋同龄人更频繁地进行 PA，这表明 SM 人群中肥胖和其他与 PA 相关的不良健康结果的更高患病率可能不是由于 PA 模式造成的。
