Abstract

BACKGROUND

In a remote rural community in central Thailand, obesity prevalence among adults significantly rose from 33.9% in 2012 to 44.8% in 2018. Limited information on weight reduction studies in Thai rural communities was available. The present study aims to evaluate the effect of daily self-weighing combined with personalized counseling in order to reduce body weight (BW) and body mass index (BMI) as well as blood pressure (BP).

METHODS

A randomized controlled trial was carried out in a rural community in central Thailand. One-hundred and seven adults were randomly allocated (1:2) to intervention and control groups. For 20 weeks, participants in the weight-loss program performed self-weighing twice daily and recorded their weight on the calendar. The program also offers weekly counseling visits by village health volunteers (VHV) who make home visits to participants. The primary outcomes were differences in mean change in BW at 20 weeks from baseline between the intervention and control groups.

RESULTS

A total of 107 participants were initially recruited. Of these, 36 participants were allocated to the intervention group and 57 participants to the control group. Significant differences in mean change in BW and BMI at the twelve-, sixteen-, and twenty-week follow-up from baseline between the two groups were observed. At twenty weeks, the mean change in BW was -1.2 kg (95% CI: -2.2, -0.3) and 0.3 kg (95% CI: -0.3, 0.8) in the intervention and control groups, respectively, with p-value = 0.007. Over 20 weeks of the study period, the estimated mean change in BW among the intervention group was 1.0 kg (95% CI -1.7, -0.2) lower than in the control group, with p-value = 0.015. Furthermore, changes in mean BMI and BP over the 20-week follow-up period in intervention participants were recognized.

CONCLUSIONS

Our study demonstrates that daily self-weighing combined with personalized counseling led by VHV is feasible and can induce weight loss among adults with obesity in a rural community. In addition, the weight-loss program may be a promising additional tool for reducing BP.

摘要

背景

在泰国中部的一个偏远农村社区，成年人肥胖率从 2012 年的 33.9%显著上升至 2018 年的 44.8%。有关泰国农村社区减肥研究的信息有限。本研究旨在评估每日自我称重与个性化咨询相结合以减轻体重（BW）和体重指数（BMI）以及血压（BP）的效果。

方法

在泰国中部的一个农村社区进行了一项随机对照试验。将 107 名成年人随机分为干预组和对照组（1:2）。在 20 周的时间里，减肥计划的参与者每天进行两次自我称重，并在日历上记录体重。该计划还提供由乡村卫生志愿者（VHV）每周进行一次咨询访问，他们会到参与者家中进行访问。主要结局指标为从基线到 20 周时干预组和对照组 BW 的平均变化差异。

结果

最初招募了 107 名参与者。其中，36 名参与者被分配到干预组，57 名参与者被分配到对照组。在从基线开始的十二、十六和二十周的随访中，两组 BW 和 BMI 的平均变化存在显著差异。二十周时，干预组 BW 的平均变化为-1.2kg（95%CI：-2.2，-0.3）和 0.3kg（95%CI：-0.3，0.8），p 值=0.007。在研究期间的 20 周内，干预组 BW 的估计平均变化比对照组低 1.0kg（95%CI -1.7，-0.2），p 值=0.015。此外，还观察到干预参与者在 20 周随访期间 BMI 和 BP 的变化。
