Abstract
- <bold>Objective: </bold>This study examined Na intake and identified the major food sources of Na in healthy Chinese adults aged ≥50 years in Hong Kong.<bold>Design: </bold>Participants who completed a baseline assessment of a randomised controlled trial assessing the effectiveness of exercise and nutrition supplementation on improving physical and cognitive functions were included. A single 24-h urine sample and a 3-d diet record were used to measure urinary Na excretion and dietary intake, respectively. The compliances to the WHO (<5 g/d) and China Nutrition Society (<6 g/d) recommendations for salt intake were assessed based on the urinary Na excretion. The relative contribution of sixteen food groups to the dietary Na intake was expressed as percentages. Associations between food groups and urinary Na excretion were analysed using multiple linear regression.<bold>Setting: </bold>Community facilities.<bold>Participants: </bold>Totally, 114 healthy Chinese adults (mean age 60·6 years, 55 % women).<bold>Results: </bold>The mean urinary Na excretion over 24-h was 2876·6 ± 1249·4 mg/d (7·3 ± 3·2 g salt/d). Overall, 22·8 % of participants met the WHO recommendation and 34·2 % met the Chinese Nutrition Society recommendation for salt intake. The major food sources of dietary Na intake were condiments (42·4 %), cereals and their products (16·8 %) and soups (13·5 %). Higher intakes of seafood and nuts were associated with lower urinary Na excretion.<bold>Conclusions: </bold>Public health strategies should target healthy Chinese adults in Hong Kong to modify the current patterns of Na intake. Targeting condiments, cereals and their products and soups will be an important strategy to reduce their Na intake. [ABSTRACT FROM AUTHOR]
