Estimation of body fat in Pakistani adult: A comparison of equations based upon skinfold thickness measurements

The effects of preventive aerobics mix on body composition in healthy adult women

The aim of this research was to determine the influence of a 12-week program of aerobics mix on the parameters of body composition in healthy adult women. The research has been performed in a sample of 64 women participants, and it is divided into two groups, an experimental group (E), made of 34 women participants (age 32 ± 1.8 years), and a control one (C), made of 30 women participants (age 33 ± 0.5 years). Their anthropometric and body composition were evaluated using the following respective parameters: body height, body weight, body fat percentage, muscle mass percentage, skinfold-back (KNL), skinfold-upper arm (KNN), skinfold-stomach (KNT), and skinfold-thigh (KNNK). After mix aerobics realization, among the women of the E group, there is a reduction of body mass by -2.5% and waist size by -3.39%, while muscle mass increased by 2.26%. With all skinfolds within the participants of the E group, there is a statistically important gained reduction of p < 0.05 at the final measuring, compared with the initial one (upper arm -21.10%, stomach -14.36%, back -20.58%, and upper leg -13.98%). The reduction of body mass percentage was -10.59%, and that of body mass index was -2.5%. Based on the gained results, it can be concluded that the mix program was efficient in the reduction of the subcutaneous fat tissue and visceral fat and also influential on the increase of muscle mass.

Internet-based platform for a low-calorie dietary intervention involving prepackaged food for weight loss in overweight and obese individuals in China: protocol for a randomised controlled trial

INTRODUCTION

Obesity is a global health issue that impacts quality of life. A calorie-restricted diet with high-intensity consultation provided via the internet may be an effective way to lose weight. The objective of this study was to assess the effectiveness of a practitioner-guided, mobile internet-based low-energy dietary intervention in overweight and obese populations in China.

METHODS AND ANALYSIS

This open-label randomised controlled trial enrolled 220 overweight and obese adults aged 18-70 years who met the inclusion criteria. Participants were assigned to the control group (n=110) or trial group (n=110). The trial group will be enrolled in the MetaWell programme, a weight loss programme using diet replacement products, wireless scales and a mobile phone app. Participants in the control group will receive paper material containing a sample diet for weight loss. The follow-up period will be 1 year, and measurements will occur at 3, 6 and 12 months. Dual-emission X-ray absorptiometry and abdominal quantitative CT will be performed to estimate the percentage of overall body fat and areas of visceral and subcutaneous fat, alongside several cardiometabolic measurements. The primary outcome of this study is the change in body mas index (BMI) at 6 months after enrolment. A mixed-effects model will be used to compare BMI and body fat changes between the two groups.

ETHICS AND DISSEMINATION

This study was approved by the ethics committee of the Hospital of Chengdu Office of the People's Government of the Tibetan Autonomous Region. Advertisements for recruitment will be sent via official accounts using WeChat. The results will be disseminated via publications in academic journals and our clinic. Our study group will maintain contact with the participants to inform them of the study findings.
