Correlation between body mass index and haemoglobin level of adolescent girls in a stunting locus area at Tangerang, Indonesia

Abstract

Introduction: In Indonesia, anaemia is known to be extremely common in female adolescents. In addition, the problem of overweight/obesity in teenagers is becoming more prevalent, even in stunting locus areas. This study aimed to examine the correlation between body mass index (BMI) and haemoglobin levels among adolescent girls in Tangerang’s stunting locus area. Methods: This crosssectional study included 171 adolescent girls attending four junior and senior high schools in Tangerang’s stunting locus area. Adolescents who matched the inclusion criteria— healthy, having lived in Sukamantri for more than six months, and willing to participate were chosen by a multistage cluster sampling procedure. Body weight and fat were measured, and Z-score for BMI-for-age was determined. Haemoglobin levels were measured by the Mission Hb Testing System. Multiple linear regression test was applied for the analysis. Results: The prevalences of thinness/severe thinness, normal, and overweight/obesity were 5.3%, 70.8%, and 23.9%, respectively. There were 20% of anaemic girls. Among anaemic girls, there were 26% overweight/obese and no thin/very thin girls. A weak, negative correlation between BMI with haemoglobin levels was observed (R2=0.054, p<0.001). Conclusion: The correlation between BMI and haemoglobin level was weak in our sample of adolescent girls in the stunting locus area. The current study emphasised the importance of additional research that includes several haematological and inflammatory biomarkers to better understand the complex relationship between nutritional status and haemoglobin level.
