【 摘 要 】

BackgroundWhether not meeting common guidelines for lifestyle behaviours is associated with weight gain is uncertain. This study examined whether 5-year weight gain was predicted by not meeting guidelines for: breakfast consumption (eating between 6 and 9 am), takeaway food consumption (<2 times/week), television viewing (<2 h/day) and daily steps (≥10,000 steps/day).MethodsOne thousand one hundred and fifty-five Australian participants (43% men, 26–36 years) completed questionnaires and wore a pedometer at baseline (2004-06) and follow-up (2009-11). Weight was measured or self-reported, with a correction factor applied. For each behaviour, participants were classified according to whether they met the guideline: consistently met at baseline and follow-up (reference group); not met at baseline but met at follow-up; met at baseline but not met at follow-up; consistently not met at baseline and follow-up. For each behaviour, weight gain was calculated using linear regression. Weight gain by number of guidelines met was also examined.ResultsMean 5-year weight gain was 2.0 kg (SD:6.3). Compared to the reference group, additional weight (mean, 95% CI) was gained among those who did not meet the guideline at follow-up, or consistently did not meet the guideline, for breakfast (1.8 kg, 0.7–2.9; 1.5 kg, 0.1–2.8); takeaway food (2.2 kg, 0.7–3.6; 1.9 kg, 0.7–3.1); watching television (1.9 kg, 0.9–2.9; 1.4 kg, 0.4–2.3); and daily steps (2.6 kg, 1.1–4.04; 1.6 kg, 0.5–2.7). Those who met ≤1 guideline at follow-up gained 3.8 kg (95% CI 2.3–5.3) more than those meeting all guidelines.ConclusionIndividuals who adopted healthier behaviours between baseline and follow-up had similar weight gain to those who met the guidelines at both time points. Encouraging young adults to meet these simple guidelines may reduce weight gain.
