| خلاصه مقاله | Introduction: Prediction of the changes in body
size and other anthropometric indices following
the weight loss is very significant in the compliance
of a weight-lowering diet. Regarding the limited
research in this area, the present study designed to
estimate the variations of anthropometric and
body composition measurements following a
weight-loss diet in overweight and obese females.
Methods: A total of 212 overweight/obese females
aged 18-60 years who adhered to an individualized
low‑calorie diet (LCD) were monitored for five
months and body weight, waist circumference
(WC), hip circumference (HC), body composition
(e.g. lean mass and fat mass), body mass index
(BMI), waist to hip ratio (WHR), waist to height
ratio (WHtR), a body shape index (ABSI), and
abdominal volume index (AVI) were determined.
Data were analyzed using Stata (Version 18.0) and
linear mixed model.
Results: A consistent decrease in anthropometric
measurements and fat mass was observed during
five-months follow-up of LCD, which were
significantly associated with weight loss except
than WHR. Furthermore, mathematical equations
demonstrated a close relationship between
percent change (PC) of body weight with decrease
of WC (PC‑WC=−0.120+0.703×PC‑WT), HC
(PC‑HC=−0.350+0.510×PC‑WT), body fat
percentage (PC‑Body Fat=−0.019+0.915×PC‑WT),
BMI (PC-BMI=−0.024+0.992×PC-WT), WHtR
(PC‑WHtR=−0.113+0.702×PC‑WT), and
improvements in ABSI
(PC‑ABSI=−0.112+0.034×PC‑WT) and AVI
(PC‑AVI=−0.324+1.320×PC‑WT).
Conclusion: The decreasing rates of WC, HC, body
fat percentage, WHtR, ABSI, and AVI in relation to
the weight loss were clinically and statistically
significant. This means that a healthy weight
lowering diet would be accompanied by reducing
the body fat, body size and the risk of morbidities. |
