BACKGROUND
Few studies have examined which lifestyle factors relate to the development of fat distribution. Therefore, the identification of the determinants of changes in fat deposition is highly relevant.
METHODS
The association between the change in physical activity (PA) and the subsequent changes in regional body fat distributions was examined. In total, 1,236 men and 1,201 women were included at baseline and participated in the Danish MONICA (MONItoring Trends and Determinants in CArdiovascular Disease) study. A questionnaire was used to assess PA at 5 and 11 years after baseline examination, while waist circumference (WC) and hip circumference (HC) were measured at both follow-ups.
RESULTS
Among men, WC increased in the constant active group to a lesser extent than in the non-constant active group (3.4 vs. 4.1 cm; p = 0.03) concerning leisure time physical activities (LTPA). A similar pattern was observed for both WC and HC in relation to occupational physical activities (OPA) (p = 0.02). Among women, the results went in the same direction for LTPA, whereas the associations with OPA were in the opposite direction (p = 0.001).
CONCLUSION
LTPA and OPA were associated with reduced subsequent 6-year changes in regional fat distribution for men. For women, no associations were observed in relation to WC; however, OPA seemed to increase HC among women.
背景
很少有研究探讨哪些生活方式因素与脂肪分布的发展有关。因此，确定脂肪沉积变化的决定因素非常重要。
方法
研究了体力活动（PA）变化与随后区域体脂分布变化之间的关系。共有 1236 名男性和 1201 名女性在基线时被纳入并参加了丹麦 MONICA（监测心血管疾病趋势和决定因素）研究。使用问卷在基线检查后 5 年和 11 年评估 PA，同时在两次随访中测量腰围（WC）和臀围（HC）。
结果
在男性中，与非持续活跃组相比，持续活跃组的 WC 在休闲时间体力活动（LTPA）中增加的幅度较小（3.4 厘米对 4.1 厘米；p = 0.03）。在职业体力活动（OPA）方面，WC 和 HC 也存在类似的模式（p = 0.02）。在女性中，LTPA 的结果方向相同，而与 OPA 的关联则相反（p = 0.001）。
结论
LTPA 和 OPA 与男性随后 6 年的区域脂肪分布变化减少有关。对于女性，WC 没有关联；然而，OPA 似乎增加了女性的 HC。
