Metabolic diseases have been shown to be associated with low vitamin D status; however, the findings have been inconsistent. Hence, the objective of our study was to investigate the relationship between vitamin D status and metabolic disease-related traits in healthy Southeast Asian women and examine whether this relationship was modified by dietary factors using a nutrigenetic study. The study included 110 Minangkabau women (age: 25–60 years) from Padang, Indonesia. Genetic risk scores (GRS) were constructed based on five vitamin D-related single nucleotide polymorphisms (SNPs) (vitamin D-GRS) and ten metabolic disease-associated SNPs (metabolic-GRS). The metabolic-GRS was significantly associated with lower 25-hydroxyvitamin D (25(OH)D) concentrations (p = 0.009) and higher body mass index (BMI) (p = 0.016). Even though the vitamin D-GRS had no effect on metabolic traits (p > 0.12), an interaction was observed between the vitamin D-GRS and carbohydrate intake (g) on body fat percentage (BFP) (p_interaction = 0.049), where those individuals who consumed a high carbohydrate diet (mean ± SD: 319 g/d ± 46) and carried >2 vitamin D-lowering risk alleles had significantly higher BFP (p = 0.016). In summary, we have replicated the association of metabolic-GRS with higher BMI and lower 25(OH)D concentrations and identified a novel interaction between vitamin D-GRS and carbohydrate intake on body fat composition.

Background: Cardiometabolic diseases are complex traits which are influenced by several single nucleotide polymorphisms (SNPs). Thus, analysing the combined effects of multiple gene variants might provide a better understanding of disease risk than using a single gene variant approach. Furthermore, studies have found that the effect of SNPs on cardiometabolic traits can be influenced by lifestyle factors, highlighting the importance of analysing gene-lifestyle interactions. Aims: In the present study, we investigated the association of 15 gene variants with cardiometabolic traits and examined whether these associations were modified by lifestyle factors such as dietary intake and physical activity. Methods: The study included 110 Minangkabau women [aged 25–60 years and body mass index (BMI) 25.13 ± 4.2 kg/m²] from Padang, Indonesia. All participants underwent a physical examination followed by anthropometric, biochemical and dietary assessments and genetic tests. A genetic risk score (GRS) was developed based on 15 cardiometabolic disease-related SNPs. The effect of GRS on cardiometabolic traits was analysed using general linear models. GRS-lifestyle interactions on continuous outcomes were tested by including the interaction term (e.g. lifestyle factor*GRS) in the regression model. Models were adjusted for age, BMI and location (rural or urban), wherever appropriate. Results: There was a significant association between GRS and BMI, where individuals carrying 6 or more risk alleles had higher BMI compared to those carrying 5 or less risk alleles (P = 0.018). Furthermore, there were significant interactions of GRS with protein intake on waist circumference (WC) and triglyceride concentrations (P_interaction = 0.002 and 0.003, respectively). Among women who had a lower protein intake (13.51 ± 1.18% of the total daily energy intake), carriers of six or more risk alleles had significantly lower WC and triglyceride concentrations compared with carriers of five or less risk alleles (P = 0.0118 and 0.002, respectively). Conclusions: Our study confirmed the association of GRS with higher BMI and further showed a significant effect of the GRS on WC and triglyceride levels through the influence of a low-protein diet. These findings suggest that following a lower protein diet, particularly in genetically predisposed individuals, might be an effective approach for addressing cardiometabolic diseases among Southeast Asian women.

Metabolic diseases result from interactions between genetic and lifestyle factors. Understanding the combined influences of single-nucleotide polymorphisms (SNPs) and lifestyle is crucial. This study employs genetic risk scores (GRS) to assess SNPs, providing insight beyond single gene/SNP studies by revealing synergistic effects. Here, we aim to investigate the association of a 23-SNP GRS with metabolic disease-related traits (obesity and type 2 diabetes) to understand if these associations are altered by lifestyle/dietary factors. For this study, 106 Minangkabau women were included and underwent physical, anthropometric, biochemical, dietary and genetic evaluations. The interaction of GRS with lifestyle factors was analyzed using linear regression models, adjusting for potential confounders. No statistically significant associations were observed between GRS and metabolic traits; however, this study demonstrates a novel interaction observed between 13-SNP GRS and monounsaturated fatty acid (MUFA) intake, and that it had an effect on HbA1c levels (p = 0.026). Minangkabau women with low MUFA intake (≤7.0 g/day) and >13 risk alleles had significantly higher HbA1c levels (p = 0.010). This finding has implications for public health, suggesting the need for large-scale studies to confirm our results before implementing dietary interventions in the Indonesian population. Identifying genetic influences on dietary response can inform personalized nutrition strategies to reduce the risk of metabolic disease.

BACKGROUND: Dadih is an Indonesian traditional fermented buffalo milk produced and consumed by the secretory immunoglobulin A (sIgA) level and nutritional status of infants aged 4–10 months. AIM: This study aims to assess the effect of dadih and zinc supplementation given to pregnant mothers for 6 months on fecal. MATERIALS AND METHODS: A prospective randomized controlled trial was conducted in two districts on 138 pregnant mothers for 6 months, randomly assigned into three groups, namely, control, dadih, combination of dadih and zinc groups. Then, the combination of groups was supplemented to expecting mothers, respectively, 6 times a week during 6 months. Anthropometric measurement and fecal sIgA of infants were assessed. RESULTS: The prevalence of nutritional status of infants who mothers were supplemented during pregnancy with dadih, dadih and zinc, and, normal diet, respectively, are 10% stunting, 5.0% underweight, and 5.0% wasting infants; and 22.5% stunted, 20.0% underweight, and 5.0% wasting infants were found in expecting mothers supplemented with it and without any supplementation (control group). The percentage of stunting in 8 months and older infants tended to reduce: 28.57%, 31.25%, and 11.76%. Their mothers were supplemented with all groups. CONCLUSION: Dadih and zinc are potential for improving nutritional status of the newborn. In addition, the two types of supplementation are recommended to pregnant mothers, to reduce the prevalence of stunting. Potential probiotic contained in Dadih which consumed in adequate amounts can help the absorption of nutrients and increase immunity of mothers and infants amounts confer a health benefit. Acceleration and growth of infants to achieve optimal growth and development should be carried out before they are under two years old.

Chronic Energy Deficiency (CED) is a major nutritional problem among pregnantwomen in developing countries, primarily due to inadequate dietary intake.Supplementary feeding interventions have been widely reported as an effectivestrategy to improve maternal nutritional status. This study aimed to evaluate the effectof high-fiber and high-protein dadih-based functional bread on Mid-Upper ArmCircumference (MUAC) among pregnant women with CED. A randomized controlledtrial was conducted involving 60 pregnant women with MUAC < 23.5 cm in PadangCity, West Sumatra. Participants were randomly allocated to an intervention groupreceiving high-fiber, high-protein dadih functional bread or a control group receivingstandard dadih functional bread for 12 weeks. MUAC was measured monthly.Independent t-tests and General Linear Model Repeated Measures were applied toassess the intervention effect, while Analysis of Covariance (ANCOVA) was used toadjust for potential covariates. Significant differences in MUAC were observed betweengroups at the third and fourth measurements (p = 0.004 and p = 0.008). Although theoverall increase in MUAC between groups was not statistically significant (p = 0.115),the intervention showed a favorable trend toward improvement. These findings indicatethat high-fiber, high-protein dadih functional bread is feasible for use among pregnantwomen with CED

Background: A hormonal contraception which considered ideal is depot medroxy progesteron acetat. There are large number of acceptors choose this contraception because this contraception is considered safe, effective, and can be used after labor. The possible side effect which can occur are increase of lipid profile, body fat percentage, and waist circumference. The purpose of this study is to see the differences between lipid profile, body fat percentage, and the waist circumference of women of childbearing age who use depot medroxy progesteron acetat injection compared with non-acceptors.Methods: This study was observational study with a cross sectional comparative approach and was conducted at the Regional Technical Services Unit (UPTD) at Regional Health Laboratory in West Sumatera Province from December 2017 until June 2018. The samples were 46 DMPA acceptors and 46 non-acceptors. The sampling method used random sampling technique. The measurements of lipid profile was conducted with colorimetric enzymatic method, which is GPO-PAP for triglycerides, and CHOD-PAP for total cholesterol, HDL and LDL. The percentage of body fat examination was conducted using Bioelectrical Impedance Analysis (BIA). The obtained data were analyzed by using t-test. Abnormal data were confirmed by Mann-whitney non-parametric test with p<0.05.Results: The results showed a significant difference between DMPA acceptors and non-acceptors (p0.05). There were significant differences in total cholesterol, LDL, triglycerides, fat percentage, body mass index, and the circumference of waist in both DMPA acceptors and non acceptors. There were no significant difference in HDL levels between DMPA acceptors and non acceptors.Conclusions: There were significant differences in total cholesterol, LDL, triglycerides, fat percentage, body mass index, and waist circumference between DMPA acceptors and non-acceptors. There was no significant difference in HDL between DMPA acceptors and non-acceptors.
