Abstract
OBJECTIVES:This present study describes weight control strategies used by a hete
rogeneous sample of US adults and their associations with weight and behaviour c
hange over time.
DESIGN:A prospective cohort study.
PARTICIPANTS:Participants for this study were 1120 US adults recruited from the
community who enrolled in a three-year intervention study to examine methods for
preventing age-related weight gain.
MEASURES:Measured body weight and self-reported behaviours related to body weigh
t (dieting practices, dietary intake and physical activity) were completed annua
lly for four years.
RESULTS:Over 70% reported using each of the following dieting strategies at leas
t once in four years: increase exercise (82.2%); decrease fat intake (78.7%); re
duce food amount (78.2%); and reduce calories (73.2%). Cumulative duration of us
e of these behaviours was brief (for example, even the most common behaviours we
re used only 20% of the time). Global reports of dieting were not predictive of
weight change over time. However, a dose–response relationship was observed bet
ween reported duration of use of several specific weight loss strategies over th
e four years and change in behaviours and weight gain.
CONCLUSIONS:These findings suggest that public health recommendations for weight
control may need to place greater emphasis on persistence of weight control beh
aviours.
一项对对1120个美国成年人的调查。
超过70%的人，在四年间都尝试过某种减肥特训。
最多的四种方法为
1. 运动 82.2% 38.8 周
2. 控制脂肪摄取 78.7% 50.0 周
3. 减少热量摄取 78.2% 34.9 周
4. 不吃甜食 73.3% 29.7 周
然而，在这篇调查报告中发现，在四年中，这些特训的持续时间都不长，持续最久的是控制
脂肪摄取的 50 周，最短是挨饿（4.1 周）
我们可以发现
1. 大部分人这些行为的持续时间都很短。
2. 越轻松执行越久
反过来说，平常的生活方式，是不是会让身形大幅度的走样，是一个值得注意的事。
