We investigated whether exposure to negative aspects of close relationships was associated with subsequent increase in body mass index (BMI) and waist circumference.
Data came from a prospective cohort study (Whitehall II) of 9425 civil servants aged 35 to 55 years at baseline (phase 1: 1985-1988). We assessed negative aspects of close relationships with the Close Persons Questionnaire (range 0-12) at phases 1 and 2 (1989-1990). We measured BMI and waist circumference at phases 3 (1991-1994) and 5 (1997-1999). Covariates at phase 1 included gender, age, marital status, ethnicity, BMI, employment grade, smoking, physical activity, fruit and vegetable consumption, and common mental disorder.
After adjustment for sociodemographic characteristics and health behaviors, participants with higher exposure to negative aspects of close relationships had a higher likelihood of a 10% or greater increase in BMI and waist circumference (odds ratios per 1-unit increase 1.08 [95% confidence interval (CI) =1.02, 1.14; P = .007] and 1.09 [CI = 1.04, 1.14; P ≤ .001], respectively) as well as a transition from the overweight (25 ≤ BMI < 30) to the obese (BMI ≥ 0) category.
Adverse social relationships may contribute to weight gain.
我们旨在探究与亲密关系的负面方面有关的暴露是否与随后的体重指数（BMI）和腰围增加有关。
数据来自一项前瞻性队列研究（Whitehall II），共有 9425 名年龄在 35 至 55 岁的公务员参加，基线期（第 1 阶段：1985-1988 年）。我们使用亲密关系问卷（Close Persons Questionnaire）在第 1 阶段和第 2 阶段（1989-1990 年）评估亲密关系的负面方面，得分范围为 0-12 分。我们在第 3 阶段（1991-1994 年）和第 5 阶段（1997-1999 年）测量 BMI 和腰围。第 1 阶段的协变量包括性别、年龄、婚姻状况、种族、BMI、职业级别、吸烟、身体活动、水果和蔬菜摄入以及常见精神障碍。
在调整社会人口特征和健康行为后，与亲密关系的负面方面接触较多的参与者更有可能出现 BMI 或腰围增加 10%或更多的情况（每增加 1 个单位的比值比分别为 1.08[95%置信区间（CI）=1.02，1.14；P=0.007]和 1.09[CI=1.04，1.14；P ≤0.001]），以及从超重（25 ≤ BMI<30）到肥胖（BMI≥0）的转变。
不良的社会关系可能会导致体重增加。
