Salt intake and salt reduction in secondary school-age students of Princess Chulabhorn's College Chiangrai (Regional Science School)
Abstract:
Salt intake and salt reduction were studied among adolescents, aged 12-18 years at Princess Chulabhorns College Chiangrai (PCCCR). This study including 813 students who were assessed during the 32 week-study period, in which nutritional therapy and nutritional education about salt intake and salt reduction were provided to obese and hypercholesterolemic students. Obesity was classified by the percentage of body fat, in this study it was found that 3.4% of the 813 students were classified as over body fat and 3.2% were of excess body fat. Analysis of the blood chemistry found that the prevalence of anemia, hyperuricemia, hypertriglyceridemia, and hypercholesterolemia were 13.5%, 46.1%, 1.4%, and 15.4%, respectively. This study analyzed the nutritional values of all food, prepared by the PCCCR school canteen, consisting of 146 main course menus and 20 desserts menus, and that the sodium in the main course menus was 32-2,497 mg/person and in the desserts menus 7-221 mg/person. Dietary sodium intake was assessed from questionnaires, and it was found that 50%-60% of students answered the sodium knowledge (SN), sodium and health (SH) questions correctly and most of the students ate bakery products and snacks (potato chips and fish snacks). After receiving the nutritional therapy based on nutritional education, the study showed that 66.7% of over and excess body fat students had a body fat reduction and 29.6% of them achieved normal body fat and 48.0% of the hypercholesterolemia students had achieved normal LDL-cholesterol levels. Moreover, the number of students who answered the SN and SH questions correctly significantly increased over the pretest results and the students had improved their behavior dietary sodium intakes. The dietary sodium intake of obese and hypercholesterolemic students was higher than the recommended Thai daily intake (Na<2,400mg/day). However, the 24-hour urinary sodium excretions were still within the normal limits. This finding may be due to sodium excretion and takes no account of electrolyte loss, other than via the kidneys, such as sweat, because most of our students spend a lot of time in the open air.
