Abstract
Background: Protein inadequacy is prevalent in developing countries because of the high consumption of starchy staple foods. Sago, as a staple food in Papua Province, was eaten with less protein. This study aimed to analyze the nutritional status of protein-energy in well-nourished adults of the moderately low protein in-take (MLP)-sago group compared to the sufficient protein intake (SP)-rice group, in lowland Mimika, Papua. Methods: This cross-sectional-analytic study was conducted on 50 participants. Twenty-four-hour food recall, body composition, albumin, and complete blood count were used to assess the nutritional status. Results: There were no differences in the body compositions and albumin levels between the MLP-sago and SP-rice groups. Multivariate linear regression showed that the mean corpuscular volume (MCV) (β = -0.524, P = 0.007) was a predictive factor for albumin in the sago group, while in the rice group, hemoglobin (β = 0.354 P = 0.089) and white blood cell counts (β = 0.396, P = 0.059) were predictive factors. Conclusions: The MLP-sago and SP-rice groups exhibited no differences in the body and visceral protein; however different predictors of albumin were found be- tween the groups, suggesting an adaptive mechanism in the MLP-sago group to maintain normal albumin levels.
Highlights
Protein is an essential element of the diet
Multivariate linear regression analysis showed that a better prediction of albumin in the rice group was featured by hemoglobin (β = 0.354, P = 0.089), and the white blood cell counts (β = 0.396, P = 0.059)
The present study showed that there were no differences in the body composition and serum albumin levels between the sago-moderately low protein and rice-sufficient protein groups
Summary
Protein is an essential element of the diet. It is required for the growth and maintenance of the 25,000 proteins that have been encoded by the human genome. Most of the proteins (70%) consumed in sub-Saharan Africa are obtained from cereals and roots[2] with diets being dominated by starchy staple foods, and nutrient-dense animal-source foods, fruits, and vegetables often being unavailable or unaffordable.[3]. Protein inadequacy is prevalent in developing countries because of the high consumption of starchy staple foods. This study aimed to analyze the nutritional status of protein-energy in wellnourished adults of the moderately low protein in-take (MLP)-sago group compared to the sufficient protein intake (SP)-rice group, in lowland Mimika, Papua. Twenty-four-hour food recall, body composition, albumin, and complete blood count were used to assess the nutritional status.
