Adequate intake of vitamin D through diet may offer benefits in terms of body composition.
We aimed to evaluate the longitudinal relationship between dietary vitamin D intake and changes in body composition in older adults over one and three years under the context of a weight loss and lifestyle behavioral intervention.
Longitudinal study.
Multicenter.
This longitudinal study included 715 aged participants (mean age 65.3 ± 5.0 years, 38% women) with overweight/obesity and metabolic syndrome.
Multivariable-adjusted mixed-effects linear regression models were fitted to investigate the longitudinal associations between dietary vitamin D intake (exposure) and body composition (outcome) with available data at baseline, one, and three years of follow-up. Data on dietary vitamin D intake was assessed using a validated 143-item food frequency questionnaire. Body composition variables (total body weight (kg), total fat mass (%), total lean mass (%), muscle-to-fat mass ratio, visceral adipose tissue (kg), and android-to-gynoid fat ratio) were measured by dual-energy X-ray absorptiometry.
Higher dietary vitamin D intake (for each μg/day) was associated with higher total lean mass (β: 0.10 %; 95% CI: 0.02 to 0.18; P: 0.017) and muscle-to-fat mass ratio (β: 1.00 × 10; 95% CI: 0.22 × 10 to 1.78 × 10; P: 0.011), and lower total body weight (β: -0.20 kg; 95% CI: -0.34 to -0.05; P: 0.007), total fat mass (β: -0.11 %; 95% CI: -0.19 to -0.02; P: 0.015), and visceral adipose tissue (β: -1.74 × 10 kg; 95% CI: -3.47 × 10 to -0.01 × 10; P: 0.048) at one year of follow-up in the group following the intervention in the multivariable-adjusted model.
Dietary vitamin D intake was associated with better body composition changes in the context of a weight loss and lifestyle intervention which led to notable changes in body composition at short term.
通过饮食摄入充足的维生素D可能对身体成分有益。
我们旨在评估在减肥和生活方式行为干预的背景下,老年人饮食中维生素D摄入量与1年和3年期间身体成分变化之间的纵向关系。
纵向研究。
多中心。
这项纵向研究纳入了715名年龄较大的参与者(平均年龄65.3±5.0岁,38%为女性),他们患有超重/肥胖和代谢综合征。
采用多变量调整的混合效应线性回归模型,利用基线、1年和3年随访时的可用数据,研究饮食中维生素D摄入量(暴露因素)与身体成分(结果)之间的纵向关联。饮食中维生素D摄入量的数据通过一份经验证的包含143个条目的食物频率问卷进行评估。身体成分变量(总体重(kg)、总脂肪量(%)、总瘦体量(%)、肌肉与脂肪量之比、内脏脂肪组织(kg)以及腹部与臀部脂肪比例)通过双能X线吸收法测量。
在多变量调整模型中,干预组随访1年时,较高的饮食维生素D摄入量(每微克/天)与较高的总瘦体量(β:0.10%;95%置信区间:0.02至0.18;P:0.017)和肌肉与脂肪量之比(β:1.00×10;95%置信区间:0.22×10至1.78×10;P:0.011)相关,与较低的总体重(β:-0.20 kg;95%置信区间:-0.34至-0.05;P:0.007)、总脂肪量(β:-0.11%;95%置信区间:-0.19至-0.02;P:0.015)和内脏脂肪组织(β:-1.74×10 kg;95%置信区间:-3.47×10至-0.01×10;P:0.048)相关。
在减肥和生活方式干预的背景下,饮食中维生素D摄入量与更好的身体成分变化相关,这种干预在短期内导致了身体成分的显著变化。
