One in five people in the world is at risk of zinc deficiency. In Indonesia, 77.48% of the population has zinc deficiency. Zinc deficiency causes sperm abnormalities, such as hypertrophy and hyperplasia of the fibrous sheath, axonal disorders, and abnormal midpiece. Serum zinc levels of infertile males were significantly lower than normal males. Factors causing a lack of serum zinc are inadequate dietary zinc intake and zinc absorption inhibitors. Serum zinc levels are influenced by unclear factors. The purpose of this study was to analyze the relationship between Body Mass Index (BMI), zinc, iron, protein, tannins and phytate intake with serum zinc levels of infertile male farmers in the Larangan district. This research was an observational study with a cross-sectional design. The sample selection used a total sampling technique of as many as 58 male infertile farmers. Data was collected through interviews using a food frequency semi-quantitative questionnaire, measurement of height using a microtoise, weighing using a digital stepping scale, and laboratory tests of venipuncture blood samples. Data analysis was performed using Pearson correlation and Spearman range. The average BMI of respondents was above the normal limit (26.09). The average zinc intake was 8.99 mg/ day, the average iron intake was 18.31 mg/day, the average protein intake was 85.71 g/ day, and the average tannin intake was 139.93 mg/day. The average phytate intake was 1147.73 mg/day and the average serum zinc level was 78.02 μg/dL. The bivariate analysis showed that there was no relationship between BMI (p-value = 0.29), zinc intake (p-value = 0.42), iron (p-value = 0.33), protein (p-value = 0.70), tannins (p-value = 0.19), and phytate (p-value = 0.63) with serum zinc levels. The average zinc intake of infertile male farmers was below the cut of nutritional adequacy rate. Infertile male farmers are advised to increase their consumption of animal zinc sources to make ends meet zinc intake per day.

Abstract

One in five people in the world is at risk of zinc deficiency. In Indonesia, 77.48% of the population has zinc deficiency. Zinc deficiency causes sperm abnormalities, such as hypertrophy and hyperplasia of the fibrous sheath, axonal disorders, and abnormal midpiece. Serum zinc levels of infertile males were significantly lower than normal males. Factors causing a lack of serum zinc are inadequate dietary zinc intake and zinc absorption inhibitors. Serum zinc levels are influenced by unclear factors. The purpose of this study was to analyze the relationship between Body Mass Index (BMI), zinc, iron, protein, tannins and phytate intake with serum zinc levels of infertile male farmers in the Larangan district. This research was an observational study with a cross-sectional design. The sample selection used a total sampling technique of as many as 58 male infertile farmers. Data was collected through interviews using a food frequency semi-quantitative questionnaire, measurement of height using a microtoise, weighing using a digital stepping scale, and laboratory tests of venipuncture blood samples. Data analysis was performed using Pearson correlation and Spearman range. The average BMI of respondents was above the normal limit (26.09). The average zinc intake was 8.99 mg/ day, the average iron intake was 18.31 mg/day, the average protein intake was 85.71 g/ day, and the average tannin intake was 139.93 mg/day. The average phytate intake was 1147.73 mg/day and the average serum zinc level was 78.02 μg/dL. The bivariate analysis showed that there was no relationship between BMI (p-value = 0.29), zinc intake (p-value = 0.42), iron (p-value = 0.33), protein (p-value = 0.70), tannins (p-value = 0.19), and phytate (p-value = 0.63) with serum zinc levels. The average zinc intake of infertile male farmers was below the cut of nutritional adequacy rate. Infertile male farmers are advised to increase their consumption of animal zinc sources to make ends meet zinc intake per day.
