Previous research has shown that involvement in meal preparation is positively associated with better diet quality. However, it is unclear whether there is an association between involvement in meal preparation and being overweight or obese. This study investigated whether the level of involvement in meal preparation was associated with objectively measured weight status in young adults. During 2004-2006, a national sample of 1,996 Australian adults aged 26 to 36 years completed a self-administered questionnaire including questions on sociodemographic characteristics, diet, and physical activity. Participants were asked to report who usually prepared the main meal on working days and responses were categorized as "myself," "shared," or "someone else." Waist circumference, weight, and height were measured by trained staff. Moderate abdominal obesity was defined as waist circumference ≥94 cm for men and ≥80 cm for women. Overweight was defined as body mass index (calculated as kg/m(2)) ≥25. Prevalence ratios were calculated using log binomial regression. After adjusting for age, education, and leisure time physical activity, men who shared the meal preparation had a slightly lower prevalence of moderate abdominal obesity (prevalence ratio=0.92; 95% confidence interval [CI]: 0.86 to 0.99) than those whose meals were usually prepared by someone else. There was no association with having sole responsibility (prevalence ratio=0.99; 95% CI: 0.92 to 1.06). There were no associations between level of involvement in meal preparation and being overweight (shared responsibility prevalence ratio=0.99; 95% CI: 0.92 to 1.07; sole responsibility prevalence ratio=0.98; 95% CI: 0.91 to 1.05). For women, level of involvement was not associated with moderate abdominal obesity (shared responsibility prevalence ratio=0.93; 95% CI: 0.84 to 1.03; sole responsibility prevalence ratio=0.94; 95% CI: 0.86 to 1.03) or being overweight (shared responsibility prevalence ratio=0.93; 95% CI: 0.84 to 1.02; sole responsibility prevalence ratio=0.93; 95% CI: 0.85 to 1.02). In this sample of young adults, level of involvement in meal preparation was not strongly related to weight status.
先前的研究表明，参与 meal preparation 与更好的饮食质量呈正相关。然而，尚不清楚参与 meal preparation 与超重或肥胖之间是否存在关联。本研究调查了参与 meal preparation 的程度与年轻成年人客观测量的体重状况之间是否存在关联。在2004年至2006年期间，对1996名年龄在26至36岁的澳大利亚成年人进行全国抽样，他们完成了一份自我管理的问卷，其中包括关于社会人口学特征、饮食和身体活动的问题。参与者被要求报告工作日通常由谁准备主餐，回答被分为“我自己”、“共同准备”或“其他人”。腰围、体重和身高由经过培训的工作人员测量。中度腹部肥胖定义为男性腰围≥94厘米，女性腰围≥80厘米。超重定义为体重指数（以千克/米²计算）≥25。使用对数二项回归计算患病率比。在调整年龄、教育程度和休闲时间身体活动后，共同准备餐食的男性中度腹部肥胖的患病率略低于餐食通常由其他人准备的男性（患病率比=0.92；95%置信区间[CI]：0.86至0.99）。独自承担准备餐食责任与患病率无关（患病率比=0.99；95%CI：0.92至1.06）。参与 meal preparation 的程度与超重之间没有关联（共同承担责任的患病率比=0.99；95%CI：0.92至1.07；独自承担责任的患病率比=0.98；95%CI：0.91至1.05）。对于女性，参与程度与中度腹部肥胖（共同承担责任的患病率比=0.93；95%CI：0.84至1.03；独自承担责任的患病率比=0.94；95%CI：0.86至1.03）或超重（共同承担责任的患病率比=0.93；95%CI：0.84至1.02；独自承担责任的患病率比=0.93；95%CI：0.85至1.02）均无关联。在这个年轻成年人样本中，参与 meal preparation 的程度与体重状况没有密切关系。
