Associations of Animal-Plant Protein Dietary Intake and Essential Amino Acid Serum Concentration with Body Fat among Adults in East Jakarta = Hubungan Konsumsi Protein Nabati-Hewani dan Konsentrasi Serum Asam Amino Essensial dengan Persen Lemak Tubuh pada Orang Dewasa di Jakarta Timur .

Obesity is becoming a serious challenge worldwide. Protein consumption is one of the important contributing factors to body fat regulation, but existing information has limitedly explored the specific type of protein and its influence for fat regulation in developing world. Therefore, we investigated the association between protein intake and its sources with obesity among Indonesian adults. This cross-sectional study involved 167 adults aged 19-50 years in urban East Jakarta through multistage random-sampling. Protein intake were collected from non-consecutive 2-day 24hour recalls that was classified as low and high intake. Body fat percentage was measured by Air Displacement Plethysmograph (BOD POD) method and classified as female obese (>33%) and male obese (>25%). Multivariate logistic-regression was performed to identify the associations between protein intake and obesity. About 69% of subjects were obese. The main sources of plant and animal protein intake came from cereals and its products (median=11.3 gr/day or 22.9% of protein intake), and white meat (median=7.85 gr/day or 15.9% of protein intake), respectively. After adjustment for marital status and sex those who had higher protein intake did not associated with being obese (Adjusted OR 1.84, pvalue=0.15). while, type of animal or plant protein intake was not associated with obesity (Adjusted OR 0.879 animal protein, p-value=0.69; OR 0.95 plant protein, p-value=0.98). The promotion of type of protein consumption must be concerning to successfully lower the prevalence of obesity in the country.

Obesitas menjadi tantangan serius di seluruh dunia. Konsumsi protein adalah salah satu faktor penting yang berkontribusi terhadap regulasi lemak tubuh, tetapi informasi yang ada telah mengeksplorasi secara terbatas jenis protein spesifik dan pengaruhnya terhadap regulasi lemak di negara berkembang. Oleh karena itu, peniliti ingin mengetahui hubungan antara asupan protein dan sumbernya dengan obesitas di kalangan orang dewasa Indonesia. Studi cross-sectional ini melibatkan 167 orang dewasa berusia 19-50 tahun di perkotaan Jakarta Timur melalui multistage random-sampling. Asupan protein dididapatkan dari repeated 24H Recall yang diklasifikasikan sebagai asupan rendah dan tinggi protein . Persentase lemak tubuh diukur dengan metode Air Displacement Plethysmograph (BOD POD) yang diklasifikasikan sebagai obesitas wanita (> 33%) dan obesitas pria (> 25%). Multivariat logistik-regresi dilakukan untuk mengidentifikasi hubungan antara asupan protein dan obesitas. Sekitar 69% subjek mengalami obesitas. Sumber utama asupan protein nabati dan hewani berasal dari sereal dan produknya (median = 11,3 gr / hari atau 22,9% dari asupan total protein), dan unggas (median = 7,85 gr / hari atau 15,9% dari asupan total protein). Setelah penyesuaian terhadap status perkawinan dan jenis kelamin mendapatkan hasil bawah asupan tinggi protein tidak berhubungan dengan obesitas (OR 1,84, p-value = 0,15), dan jenis asupan protein hewani atau nabati juga tidak berhubungan dengan obesitas (OR protein hewan 0879, p-value = 0,69; OR protein nabati 0,95, p-value = 0,98). Promosi jenis konsumsi protein harus diperhatikan agar berhasil menurunkan prevalensi obesitas di negara ini.
