Abstract

Background: Differences in body composition across adulthood are associated with increased metabolic risk and functional decline. Although body mass index (BMI) is widely used to assess nutritional status, it has limitations in distinguishing adiposity from skeletal muscle mass. Objective: This study aimed to analyze differences in body composition according to age and sex, and to examine the associations between age and BMI, total body fat, visceral fat, and skeletal muscle mass among Indonesian adults. Methods: A cross-sectional study was conducted among 282 adults aged ≥18 years using purposive sampling. Body composition was assessed using bioelectrical impedance analysis. Statistical analyses included Spearman’s rho correlation, Kruskal–Wallis test, and ordinal logistic regression. Results: A total of 51.1% of participants were classified as obese, while 77.3% exhibited low skeletal muscle mass. Age was positively correlated with total body fat (ρ = 0.259; p < 0.001) and visceral fat (ρ = 0.267; p < 0.001), and negatively correlated with skeletal muscle mass (ρ = −0.294; p < 0.001). Middle-aged adults demonstrated the highest adiposity levels, whereas younger adults exhibited higher skeletal muscle mass. Conclusion: Older age was associated with increased adiposity and reduced skeletal muscle mass. Comprehensive body composition assessment is important to support early identification of metabolic risk and sarcopenic obesity.

Abstract

Latar Belakang: Dunia masih saja terus berperang melawan Covid-19 dan telah banyak upaya yang dilakukan untuk menyembuhkan dunia dari Covid-19, salah satunya ialah dengan vaksinasi. Saat ini vaksinasi sudah mudah didapatkan dan masyarakat juga sudah memiliki pemikiran yang terbuka terhadap vaksinasi, namun bagaimana persepsi masyarakat tersebut dalam menerima vaksinasi Covid-19 tentunya berbeda-beda, dilatarbelakangi pula oleh pengetahuan dan pengalaman yang berbeda-beda. Tujuan: Mengetahui bagaimana persepsi mahasiswa Universitas Advent Indonesia terhadap vaksinasi Covid-19. Metode: Penelitian kualitatif dengan metode cross sectional. Teknik penentuan sampel menggunakan metode simple random sampling, dengan jumlah responden sebanyak 96 orang dari total populasi sebanyak 120 orang yang merupakan mahasiswa berasrama di Universitas Advent Indonesia. Data diperoleh dari pembagaian kuesioner secara langsung kepada responden pada bulan November-Desember 2021. Analisis data menggunakan uji chi square. Hasil: Rata-rata responden memiliki persespsi yang positif terhadap vaksinasi Covid-19, dengan nilai rata-rata 12.22. Nilai skor >8 dari total skor 17 menandakan bahwa rata-rata responden memiliki persespsi yang positif terhadap vaksinasi Covid-19. Kesimpulan: Persepsi positif mahasiswa Universitas Advent Indonesia terhadap vaksinasi Covid-19 dipengaruhi oleh faktor jenis kelamin, latar belakang pengetahuan, riwayat memiliki penyakit tidak menular, dan riwyat pernah terkena Covid-19. Saran: Bagi peneliti selanjutnya diharapkan untuk melakukan penelitian yang terkait namun dengan menggunakan studi kualitatif dan metode wawancara mendalam.

Abstract

Hypertension is influenced by multiple biological and behavioral factors; however, the relative contributions of body age and body composition remain unclear. This study examined the associations of lifestyle behaviors, body age, and body composition with blood pressure among 167 adults in Indonesia using a cross-sectional design. Lifestyle score, body age, body mass index (BMI), skeletal muscle mass, total body fat percentage, and blood pressure were assessed using standardized procedures. Spearman correlation and multiple linear regression analyses were performed. Body age was the only significant predictor of systolic blood pressure (β = .311, p = .002). In contrast, skeletal muscle mass (β = .172, p = .030) and total body fat percentage (β = .248, p = .017) were significant positive predictors of diastolic blood pressure. Lifestyle score and BMI were not significant predictors in the regression models. These findings suggest that physiological aging and body composition are more strongly associated with blood pressure than lifestyle behaviors. Incorporating body age and body composition assessments into cardiovascular risk screening may improve hypertension prevention and early intervention strategies.
