Abstract

Objectives: This study evaluates the effect of a 3-month calorie restriction (CR) without snacking on the anthropometric parameters, Homeostatic Model Assesment of Insulin Resistance (HOMA-IR), and lipid profiles of female office workers with overweight or obesity, whose physical activity was limited during the COVID-19 pandemic lockdown.

Material and methods: Forty-eight women aged 20-38 years (28.9±5.24) with low physical activity levels were divided into a non-snacking (NS) group (N = 21) and a snacking (S) group (N = 27) prior to the dietary intervention. Their daily energy intake during the intervention was lowered by 30% compared with the baseline level, and the proportion of polyunsaturated fatty acids and fiber in their diet was increased (to >30 g/day). The proportion of saturated fatty acids and simple carbohydrates was also reduced. The study participants were assessed at the baseline and post-intervention for anthropometric variables (body weight, body fat percentage BMI, waist circumference, hip circumference, waist-to-hip ratio) and the concentrations of insulin, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Moreover, the values for HOMA-IR, the atherogenic index of plasma (AIP), and the ratios of TC/HDL-C, TG/HDL-C, and LDL-C/HDL-C were calculated.

Results: All anthropometric parameter values obtained post-intervention were lower than the baseline in both groups. The serum insulin concentration and HOMA-IR decreased respectively by an average of 6% and 25% in the NS group and 37% and 45% in the S group. The lipid profiles of all participants improved significantly, with the LDL-C concentration showing a more promising trend in the S group (decrease by 27%) than in the NS group (17%).

Conclusions: The study showed that CR improved the anthropometric parameters, HOMA-IR index, and lipid profiles of all participants. Int J Occup Med Environ Health. 2022;35(6):693-706.

卡路里限制对超重和肥胖女性办公室工作人员人体测量参数、HOMA-IR指数和脂质谱的影响:初步研究。
目的:本研究评估了3个月不吃零食的卡路里限制(CR)对人体测量参数、胰岛素抵抗稳态模型评估(HOMA-IR)和脂质特征的影响,超重或肥胖的女性办公室职员在COVID-19大流行期间的身体活动受到限制。材料与方法:48名年龄在20 ~ 38岁(28.9±5.24),体力活动水平较低的女性在饮食干预前分为不吃零食组(N = 21)和吃零食组(N = 27)。与基线水平相比,他们在干预期间的每日能量摄入量降低了30%,饮食中多不饱和脂肪酸和纤维的比例增加(>30 g/天)。饱和脂肪酸和简单碳水化合物的比例也有所降低。在基线和干预后对研究参与者进行人体测量变量(体重、体脂百分比BMI、腰围、臀围、腰臀比)和胰岛素、总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)的浓度评估。计算HOMA-IR、血浆动脉粥样硬化指数(AIP)、TC/HDL-C、TG/HDL-C、LDL-C/HDL-C比值。结果:两组干预后获得的所有人体测量参数值均低于基线。NS组血清胰岛素浓度和HOMA-IR分别平均下降6%和25%,S组平均下降37%和45%。所有参与者的脂质谱均有显著改善,其中S组的LDL-C浓度比NS组(降低了17%)更有希望(降低了27%)。结论:研究表明,CR改善了所有参与者的人体测量参数、HOMA-IR指数和脂质谱。中华医学杂志,2010;35(6):693-706。
