Regular physical activity is a key way to prevent disease. However, we have a limited understanding of the socioeconomic precursors and glucoregulatory sequelae of engaging in physical activity in different domains.
We examined the associations among life course socioeconomic disadvantage; meeting the physical activity guidelines with leisure-time physical activity, occupational physical activity, or household physical activity; and prediabetes and diabetes in the Midlife in the United States national study (N = 986).
Childhood disadvantage was associated with lower odds of meeting the guidelines with leisure-time physical activity (odds ratio = 0.75; 95% confidence interval, 0.65-0.86). Adulthood disadvantage was associated with higher odds of meeting the guidelines with occupational physical activity (odds ratio = 1.94; 95% confidence interval, 1.49-2.53). Importantly, while meeting the guidelines with leisure-time physical activity was associated with lower odds of prediabetes and diabetes, we found no evidence for associations among occupational physical activity, household physical activity, and glucoregulation.
Current US physical activity guidelines do not differentiate between physical activity for leisure or work, assuming that physical activity in any domain confers comparable health benefits. We documented important differences in the associations among lifetime socioeconomic disadvantage, physical activity domain, and diabetes, suggesting that physical activity domain potentially belongs in the guidelines, similar to other characteristics of activity (eg, type, intensity).
规律的体育活动是预防疾病的关键途径。然而，我们对不同领域体育活动的社会经济先兆和糖调节后遗症了解有限。
在美国中年全国性研究（N = 986）中，我们研究了生命历程中的社会经济劣势、通过休闲体育活动、职业体育活动或家务体育活动达到体育活动指南要求，与糖尿病前期和糖尿病之间的关联。
童年劣势与通过休闲体育活动达到指南要求的较低几率相关（优势比 = 0.75；95%置信区间，0.65 - 0.86）。成年劣势与通过职业体育活动达到指南要求的较高几率相关（优势比 = 1.94；95%置信区间，1.49 - 2.53）。重要的是，虽然通过休闲体育活动达到指南要求与糖尿病前期和糖尿病的较低几率相关，但我们没有发现职业体育活动、家务体育活动与糖调节之间存在关联的证据。
美国当前的体育活动指南没有区分休闲或工作中的体育活动，假设任何领域的体育活动都能带来相当的健康益处。我们记录了一生社会经济劣势、体育活动领域和糖尿病之间关联的重要差异，表明体育活动领域可能应纳入指南，类似于活动的其他特征（如类型、强度）。
