Obesitas sentral atau abdominal obesity merupakan kondisi tubuh yang mengalami akumulasi lemak di bagian tengah perut (intra-abdominal fat) yang merupakan faktor utama terjadinya insidens penyakit kardiovaskular dan sindrom metabolik. Prevalensi obesitas sentral terus meningkat termasuk di Jakarta. Berbagai penelitian menunjukkan bahwa pola makan vegetarian memiliki risiko lebih rendah mengalami obesitas sentral. Adapun, penelitian mengenai obesitas sentral pada kelompok vegetarian di Indonesia masih terbatas. Penelitian ini bertujuan untuk mengetahui prevalensi obesitas sentral dan hubungan antara jenis diet vegetarian dan faktor lainnya yang berhubungan dengan obesitas sentral pada kelompok dewasa vegetarian dan non-vegetarian usia 20-59 tahun di Pusdiklat Buddhis Maitreyawira dan Vihara Prajna Dhyana Jakarta tahun 2024. Penelitian ini dilakukan dengan metode cross-sectional dengan melibatkan 139 responden. Pengambilan data dilakukan pada bulan Maret sampai April 2024 dengan metode purposive sampling. Hasil penelitian menunjukkan bahwa 51,8% responden tergolong obesitas sentral dengan proporsi obesitas sentral pada non-vegetarian (70,0%) dibandingkan vegetarian (46,8%). Hasil analisis bivariat menunjukkan adanya hubungan antara pola makan vegetarian dan non-vegetarian (p-value 0,041), usia (p-value 0,001), status pernikahan (p-value 0,011), asupan energi (p-value 0,002), asupan protein (p-value 0,034), asupan lemak (p-value ≤0.001), aktivitas fisik (p-value ≤0,001), kebiasaan mengemil (p-value 0,004), dan durasi tidur (p-value ≤0,001) dengan obesitas sentral. Namun, tidak berhubungan dengan jenis kelamin, tingkat pendidikan, asupan karbohidrat, kebiasaan konsumsi fast food, makanan/minuman manis, dan gorengan.

Central obesity or abdominal obesity is a body condition that experiences fat accumulation in the middle of the abdomen (intra-abdominal fat) which is a major factor in the incidence of cardiovascular disease and metabolic syndrome. The prevalence of central obesity continues to increase, including in Jakarta. Various studies show that a vegetarian diet has a lower risk of central obesity. Meanwhile, research on central obesity in vegetarian groups in Indonesia is still limited. This study aims to determine the prevalence of central obesity and the relationship between the type of vegetarian diet and other factors related to central obesity in a group of vegetarian and non-vegetarian adults aged 20-59 years at the Maitreyawira Buddhist Education and Training Center and the Prajna Dhyana Vihara Jakarta in 2024. This research was conducted using a cross-sectional method involving 139 respondents. Data collection was carried out from March to April 2024 using the purposive sampling method. The results showed that 51.8% of respondents were classified as central obese with the proportion of central obesity in non-vegetarians (70.0%) compared to vegetarians (46.8%). The results of bivariate analysis showed a relationship between vegetarian and non-vegetarian diets (p-value 0.041), age (p-value 0.001), marital status (p-value 0.011), energy intake (p-value 0.002), protein intake ( p-value 0.034), fat intake (p-value ≤0.001), physical activity (p-value ≤0.001), snacking habits (p-value 0.004), and sleep duration (p-value ≤0.001) with central obesity. However, it is not related to gender, education level, carbohydrate intake, fast food consumption habits, sweet foods/drinks, and fried foods.
