关爱女性：越抑郁，越肥胖

据美国国家卫生统计中心（NCHS）对国家健康和营养调查项目2005-2010年收集资料的调查分析发现，不同年龄段抑郁和非抑郁女性的肥胖发生率有显著差异。20～39岁年龄段，肥胖发生率分别为45%和30%；40～59岁年龄段，肥胖发生率分别为49%和38%； 60岁以上女性，肥胖发生率分别为47%和37%。而在抑郁和非抑郁男性人群中，只有60岁以上的肥胖率有显著差异，分别为47%和35%。综上，成年抑郁和非抑郁人群的肥胖发生率分别为43%和33%。

该调查报告引用了一项肥胖率在民族或种族间无统计学差异（非西班牙裔白人妇女除外）的研究，该研究报道了45%的抑郁患者和32%的非抑郁患者均为肥胖者。

另外，NCHS发现，不论是否存在抑郁症状或其严重程度如何，与未服用抗抑郁药人人群相比，服用抗抑郁药的患者更容易肥胖。该报告还引用了另一项研究，该研究报告在服用抗抑郁药的中度至重度抑郁症患者有近55%肥胖率，且该比例与未服用抗抑郁药的同类患者高出16%；服用抗抑郁药的轻度或无症状患者中肥胖率仅为38%，比未服药者高出5%。

该调查报告认为，目前无法确认抑郁和肥胖的因果关系，因为“两者是同时被观察到的。”

A significant statistical difference was found in obesity rates for all identified age groups of women. For women aged 20-39, 45% of those who were depressed were obese, compared with 30% of nondepressed women. Among women aged 40-59, 49% of depressed women were obese, compared with 38% of nondepressed women, and among women over 60, 47% of depressed women were obese, compared with 37% of nondepressed women.

Among depressed men, only those over 60 had a significant difference in obesity rates, at 47%, compared with 35% of nondepressed men, the NCHS found. Overall, 43% of adults with depression were obese, compared with 33% of adults who were not depressed.

The report cited no statistical differences in obesity rates by ethnicity or race except for non-Hispanic white women. Among that group, 45% of those who were depressed were obese, and 32% of those who were not depressed were obese.

In addition, the NCHS found, adults who were taking antidepressants were more likely to be obese than those who were not taking antidepressants, regardless of the severity or presence of depressive symptoms. The report cited an obesity rate of nearly 55% for adults with moderate to severe depressive symptoms who also were taking antidepressants; that rate was 16% higher than it was for people with similar symptoms but not taking antidepressants, the NCHS reported. People with mild to no depressive symptoms who were taking antidepressants had an obesity rate of 38%. That was 5% higher than it was for those not on antidepressants but with similar symptoms.

It could not be determined whether depression or obesity occurred first, the report said, because “they were both measured at the same time.”

The NCHS study used data collected from the National Health and Nutrition Examination Survey.
