Associations among blood pressure, salt consumption and body weight status of students from south-western Ontario

Abstract

Objective: The purpose was to examine the associations among body weight status, blood pressure and daily Na intake among grade 7 students from south-western Ontario, Canada. Design: Cross-sectional. Data were collected using the Food Behaviour Questionnaire, including a 24 h diet recall. Measured height and weight were used to determine BMI. Blood pressure was taken manually using mercury sphygmomanometers. Setting: Twenty-six schools in south-western Ontario, Canada. Subjects: Grade 7 students (n 1068). Results: Body weight status indicated 1 % were underweight, 56 % normal weight, 23 % overweight and 20 % were obese. Mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 108?3 (SD 10?3) mmHg and 66?0 (SD 7?5) mmHg, respectively, and mean Na intake was 2799 (SD 1539) mg/d. Bivariate analyses suggested that SBP (P , 0?001) and DBP (P , 0?001) were significantly different by body weight status, yet no associations were observed for Na. Adjusted for gender, ethnicity and under-reporting, participants were more likely to be overweight/obese if they had higher SBP (v. lower: OR 5 1?06, 95 % CI 1?05, 1?08, P , 0?001), higher DBP (v. lower: OR 5 1?02, 95 % CI 1?00, 1?04, P 5 0?043) and higher intakes of Na (3rd v. 1st quartile: OR 5 1?72, 95 % CI 1?14, 2?59, P 5 0?009; 4th v. 1st quartile: OR 5 2?88, 95 % CI, 1?76, 4?73, P , 0?001). Conclusions: High intakes of Na, coupled with high SBP and DBP, were associated with overweight and obesity status among the grade 7 sample from south-western Ontario, Canada.

Sodium intake is associated with increased disease activity in multiple sclerosis

“…However, we ruled out this possibility by measuring the sodium concentration in the serum and by excluding patients with hyponatraemia. There is evidence that sodium intake is linked to obesity and changes in body fat composition,19 and although obesity has been linked to MS risk, appear to occur in childhood and adolescence 20. Nevertheless, we included this variable in our adjusted models to account for potential confounding factors.…”

Association of the urinary sodium to urinary specific gravity ratio with metabolic syndrome in Korean children and adolescents: The Korea National Health and Nutrition Examination Survey 2010-2013

“…A recent Korean study demonstrated that the estimated 24-hour urine excretion of sodium, which was used as a surrogate of sodium intake, is associated with MetS and its components [ 25 ]. Some studies conducted in pediatric fields have indicated that high sodium intake is related to obesity and hypertension [ 15 , 26 , 27 ], but few studies have evaluated the association of sodium intake with MetS and its components with the exception of elevated BP. In this study, after adjusting for confounders, we performed multivariate logistic regression analyses and demonstrated that boys with a U-Na to U-SG ratio in the highest quartile exhibited significantly higher risks for elevated TG and MetS compared with those with a U-Na to U-SG ratio in the lowest quartile.…”

Prevalence of some modified cardiovascular risk factors among young students

“…Вейнбергер [44], который изучал сольчувстви-тельность, установил, что среди лиц с нормальным АД моложе 30 лет сольчувствительными являются 35%, и это делает чрезвычайно важным изучение потребления пова-ренной соли среди молодых людей.
