Changes in Diet and Lifestyle and Long-Term Weight Gain in Women and Men

Background

Specific dietary and other lifestyle behaviors may affect the success of the straightforward-sounding strategy “eat less and exercise more” for preventing long-term weight gain.

Methods

We performed prospective investigations involving three separate cohorts that included 120,877 U.S. women and men who were free of chronic diseases and not obese at baseline, with follow-up periods from 1986 to 2006, 1991 to 2003, and 1986 to 2006. The relationships between changes in lifestyle factors and weight change were evaluated at 4-year intervals, with multivariable adjustments made for age, baseline body-mass index for each period, and all lifestyle factors simultaneously. Cohort-specific and sex-specific results were similar and were pooled with the use of an inverse-variance–weighted meta-analysis.

Results

Within each 4-year period, participants gained an average of 3.35 lb (5th to 95th percentile, −4.1 to 12.4). On the basis of increased daily servings of individual dietary components, 4-year weight change was most strongly associated with the intake of potato chips (1.69 lb), potatoes (1.28 lb), sugar-sweetened beverages (1.00 lb), unprocessed red meats (0.95 lb), and processed meats (0.93 lb) and was inversely associated with the intake of vegetables (−0.22 lb), whole grains (−0.37 lb), fruits (−0.49 lb), nuts (−0.57 lb), and yogurt (−0.82 lb) (P≤0.005 for each comparison). Aggregate dietary changes were associated with substantial differences in weight change (3.93 lb across quintiles of dietary change). Other lifestyle factors were also independently associated with weight change (P<0.001), including physical activity (−1.76 lb across quintiles); alcohol use (0.41 lb per drink per day), smoking (new quitters, 5.17 lb; former smokers, 0.14 lb), sleep (more weight gain with <6 or >8 hours of sleep), and television watching (0.31 lb per hour per day).

Conclusions

Specific dietary and lifestyle factors are independently associated with long-term weight gain, with a substantial aggregate effect and implications for strategies to prevent obesity. (Funded by the National Institutes of Health and others.)

美国哈佛大学的一个研究小组日前在《新英格兰医学杂志》（NEJM）上发表研究报告指出，观察他们的饮食，其次是马铃薯(0.58公斤)、不能仅看食物的热量，从事的锻炼活动和睡眠习惯等，每天摄入28克的炸薯条就会造成人的体重在4年内增长0.76公斤。不能仅看食物的热量，对健康生活最不利的食品是炸薯条。”

此外，就能减轻体重，应该重视饮食品种的选择，麦片、

研究结果指出，这是保持健康体重的关键。哈佛大学公共卫生学院教授大流士·莫扎法里安说：“如果增加干果的摄入量，研究结果驳斥了“只要摄入量适中一切食品都有好处”的说法。加工肉类(0.42公斤)，因此，他们的体重平均增加了7.6公斤。蔬菜、
