Komposisi Lemak Viseral, Basal Metabolic Rate (BMR), Dan Usia Sel Terhadap Indeks Masa Tubuh (IMT) Pada Remaja

Abstract

ABSTRAK

Status gizi remaja dapat dihitung berdasarkan Indeks Masa Tubuh (IMT). Konsumsi makanan yang buruk pada remaja yang tinggi kalori dan rendah serat dapat menyebabkan ketidakseimbangan antara asupan dan luaran energi yang dapat menyebabkan pertambahan berat badan. Proporsi overweight usia > 18 tahun terus mengalami peningkatan sejak tahun 2007, 2013  dan  2018 yaitu 8.6%  11.5%  dan 13.6%. Hipotesis untuk mengetahui Indeks Massa Tubuh(IMT) dan hubungannya terhadap Basal Metabolisme Rate (BMR), lemak visceral dan usia sel pada kelompok remaja. Metode penelitian kuantitatif dengan pendekatan cross sectional dengan sampel lulusan SMU yang mendaftar ke Universitas MH. Thamrin berjumlah 42 responden yang diambil secara Accidental. Hasil Penelitian  berdasarkan  Indeks Masa Tubuh(IMT) adalah 61.9% kategori normal sedangkan 21,4% mengalami overweight dan 16,7 % underweight, rata-rata BMR dari responden adalah 1384 Kkal (95% CI 1312.2-1456.5) dengan Standar Deviasi 231,5 serta 61.9% memiliki lemak visceral normal dan 38.1% memiliki lemak visceral tidak normal, 78.6% memiliki usia sel lebih muda/sesuai usia kronologisnya dan 21.4% memiliki usia sel lebih tua dari usia kronologisnya. Remaja overweight dengan usia sel lebih tua dari usia kronologisnya dapat dijadikan skrining untuk melakukan modifikasi gaya hidup dan perilaku hidup sehat.

ABSTRACT

The nutritional status of adolescent can be calculated based on the Body Mass Index (BMI).  Poor consumption of foods in adolescents that are high in calories and low in fiber can cause an imbalance betweet energy intake and output which can lead to weight gain.  The proportion of overweight aged > 18 years has continued to increase since 2007, 2013 and 2018, namely 8.6%, 11.5% and 13.6%.  the hypothesis is to determine the Body Mass Index (BMI) and its relationship to the Basal Metabolic Rate (BMR), veceral fat and cell age in the adolescent group.  Quantitative research method with cross sectional approach with a sample of high school graduates who enrolled in MH. Thamrin University amounted to 42 respondents who were taken by accident. The results of the study based on the Body Mass Index (BMI) were 61.9% in the normal category while 21.4% were overweight and 16.7%  were underweight, the average BMR of the respondent was 1384 Kkal (95%CI 1312.2-1456.5) with Standart Deviation of 231,5 and 61.9% had a normal visceral fat and 38.1% had abnormal visceral fat, 78.6% had younger cell age /chronological age and 21.4% had cell age older than chronological age.  Overweight adolescent with cell age older than chronological age can be used as screening to make lifestyle modifications and healthy living behaviors.

Key words: BMI, visceral fat, cell age
