Association of zinc intake & serum zinc levels with acne severity

BACKGROUND: Children in rural areas are susceptible to zinc deficiency. Zinc deficiency in children can affect cognitive function in children. Zinc plays a role in cellular function and critical brain growth processes, including cell replication, DNA and RNA synthesis, and the release of neurotransmitters. AIM: This study aimed to analyze the condition of zinc deficiency and its relationship with the level of intelligence in children in rural areas. METHODS: The study design was cross-sectional, with a sample of 44 elementary school children aged 9–12 years taken randomly. Blood was drawn to measure serum Zn-levels, and serum Zn-levels were measured using Colorimetric Assay Kit (E-BC-K137). Zinc intake data were obtained from the food recall form, which was carried out 3 × 24 h. The level of intelligence is measured by the Culture Fair Intelligence Test method. The sample characteristics data obtained through a questionnaire. Furthermore, the data were analyzed using the Chi-square test. RESULTS: About 84.2% of children with insufficient zinc intake had low serum Zn-levels. There was a significant relationship between zinc intake and serum zinc levels (p = 0.026; PR = 4.293). Children with low serum zinc levels of 96.5% have intelligence levels below average. There was a significant relationship between serum zinc levels and intelligence level as well (p = 0.001; PR = 24,500). CONCLUSION: Zinc deficiency in children is characterized by low serum Zn-levels. Low serum Zn-level is caused by low zinc intake, thus children with low serum Zn-levels are at risk of having intelligence level below average. Therefore, health education about the importance of zinc intake in children should be given to parents, so that the incidence of zinc deficiency in children can be reduced.

Serum Zinc Levels

Background: School-age children are at risk of zinc deficiency which can be identified by measuring serum zinc levels. Zinc intake, in particular, strongly affects zinc absorption and consequently alters serum zinc concentration. Phytate is the strongest inhibitor of zinc absorption. The scale of its inhibitory ability can be measured through phytate:zinc molar ratio. This study aimed to describe phytate:zinc molar ratio in school-age children in coastal area of Semarang.Method: This was a cross-sectional study on 50 samples of children aged 9-12 years chosen by non probability sampling from several elementary schools in Semarang. Observed data include subject characteristics, zinc intake, phytate intake, and serum zinc levels. Participants' intake was assessed using 3x24 hour food recall and food record, while serum zinc levels were evaluated through Atomic Absorbant Spechtrophotomety (AAS) methods. Data was analyzed by Pearson’s test.Result: The mean serum zinc level was 93,85±22,99 µg/dl, with a phytate:zinc molar ratio of 14,48±4,23. Only 14% of the subjects had low zinc serum levels, but there was 46% with low zinc absorption rates according to their molar ratio of phytate:zinc. No significant correlation was detected between phytate:zinc molar ratio and serum zinc levels (p=0,427). Conclusion: Low zinc serum levels was found in 14% of the subjects while 46% had low zinc absorption rate. No significant correlation was detected between phytate:zinc molar ratio and serum zinc levels.

Serum Zinc Levels

Diastolic dysfunction is an emerging challenge among hemodialysis (HD) patients, and the associations between serum zinc with echocardiographic parameters and diastolic function remain uncertain. A total of 185 maintenance HD patients were stratified by the tertiles of serum zinc level to compare their clinical characteristics and echocardiography. Correlations of serum zinc levels with echocardiographic parameters were examined using Pearson’s analysis. Univariate and multivariate logistic regression analyses were performed to investigate the determinants of E/e’ ratio >15 and left atrial volume index (LAVI) > 34 mL/m2, both indicators of diastolic dysfunction. Patients belonging to the first tertile of serum zinc level had a significantly higher E/e’ ratio and LAVI. Serum zinc levels were negatively correlated with E (r = −0.204, p = 0.005), E/e’ ratio (r = −0.217, p = 0.003), and LAVI (r = −0.197, p = 0.007). In a multivariate analysis, older age, diabetes, coronary artery disease, and lower serum zinc levels (OR = 0.974, 95% CI = 0.950–0.999, p = 0.039) were significantly associated with E/e’ ratio >15. Furthermore, diabetes and lower serum zinc levels (OR = 0.978, 95% CI = 0.958–0.999, p = 0.041) were significantly associated with LAVI >34 mL/m2. Reduced serum zinc level was significantly associated with diastolic dysfunction among HD patients. Further prospective studies are warranted to investigate whether zinc supplementation can attenuate cardiac dysfunction in maintenance HD patients.

Serum Zinc Levels

Background: The relationships between serum zinc levels and body composition or clinical outcomes of incident hemodialysis (HD) patients remain unclear. Methods: This prospective observational study examined the relationships between serum zinc levels and clinical indexes, including body composition, in 142 incident HD patients using a bioelectrical impedance analysis. Patients were divided into three groups according to baseline serum zinc levels: tertile, <45, 45–59, and ≥60 µg/dL. The reference group was set as ≥60 µg/dL. Cox’s regression analysis was performed to investigate the relationships between serum zinc categories and cardiovascular events and all-cause mortality after adjustments for potential confounders. Results: Serum zinc levels positively correlated with the nutritional index and negatively correlated with fluid volume markers. In a mean follow-up of 2.5 years, there were 20 cases of cardiovascular events and 15 of all-cause mortality. In the Cox’s regression analysis for cardiovascular events and all-cause mortality, the hazard ratio increased with a decrease in serum zinc levels, but was not significant. Conclusion: Serum zinc levels were associated with nutritional and fluid volume markers in incident HD patients. To clarify the relationship between serum zinc levels and cardiovascular events or mortality, further studies with a larger number of cases will be necessary.
