Breakfast skipping is reported to be associated with obesity in children and younger populations; however, few studies report the association among elderly. The purpose of this study was to investigate the relationships between breakfast skipping and obesity prevalence among elderly.
Cross-sectional study.
Community-dwelling elderly in Nara, Japan.
1052 elderly participants (mean age: 71.6 years).
Obesity and breakfast skipping were defined as body mass index of ≥25 kg/m2 and skipping breakfast one or more times per week, respectively.
Two hundred and seventy-two participants (25.9%) were classified as obese and forty-one (3.9%) were as breakfast skippers. Obesity prevalence was significantly higher in breakfast skippers than in breakfast eaters (43.9% vs. 25.1%, P = 0.007). In multivariable logistic regression analysis adjusted for potential confounders (age, sex and alcohol consumption), breakfast skippers showed significantly higher odds ratio (OR) for obesity than breakfast eaters (OR, 2.23; 95% confidence interval, 1.17-4.27; P = 0.015), which continued to be significant after further adjustment for socioeconomic status. In addition, breakfast skippers showed significantly lower daily potassium (P <0.001) and dietary fibre intakes (P = 0.001) and lower subjective physical activity (P = 0.035) than breakfast eaters.
Breakfast skipping was significantly associated with obesity among elderly. Poor diet quality and physical inactivity may be potential intermediators underlying the association between breakfast skipping and obesity.
据报道，不吃早餐与儿童及较年轻人群的肥胖有关；然而，很少有研究报道老年人中二者的关联。本研究的目的是调查老年人不吃早餐与肥胖患病率之间的关系。
横断面研究。
日本奈良的社区老年人。
1052名老年参与者（平均年龄：71.6岁）。
肥胖和不吃早餐分别定义为体重指数≥25kg/m²和每周不吃早餐一次或多次。
272名参与者（25.9%）被归类为肥胖，41名（3.9%）为不吃早餐者。不吃早餐者的肥胖患病率显著高于吃早餐者（43.9%对25.1%，P = 0.007）。在对潜在混杂因素（年龄、性别和饮酒）进行调整的多变量逻辑回归分析中，不吃早餐者患肥胖的比值比（OR）显著高于吃早餐者（OR，2.23；95%置信区间，1.17 - 4.27；P = 0.015），在进一步调整社会经济地位后仍具有显著性。此外，不吃早餐者的每日钾摄入量（P < 0.001）和膳食纤维摄入量（P = 0.001）显著低于吃早餐者，主观体力活动也较低（P = 0.035）。
老年人不吃早餐与肥胖显著相关。饮食质量差和身体活动不足可能是不吃早餐与肥胖之间关联的潜在中介因素。
