简介：最近的研究表明，富含钠的饮食可能直接导致肥胖，或者与食用促进体重增加的食物有关。目的：本研究的目的是分析尿钠与体重超标之间的关系。此外，该研究还调查了盐摄入量与饮食习惯之间的关系，因为高盐摄入量可能与饮食习惯不当和肥胖发生率高有关。 方法：这项研究涉及 418 名年龄在 18 至 60 岁的成年人（196 名男性和 222 名女性）。测量体重、身高和腰围，并计算体重指数和腰围/身高比。使用连续两天的“24 小时回忆”估算膳食摄入量，并从 24 小时尿液样本中测定钠含量。 结果：34.4% 的人口超重，13.6% 肥胖。 BMI 与尿钠浓度呈正相关。尿钠值也与其他肥胖指标（例如腰围和腰/身高比）呈正相关。尿钠排泄量a≥154 mmol/l（百分位50）的个体的体重、BMI、腰围和腰/身高比较高（P50）。此外，该组的个体呈现出较高的热量摄入量和总食物摄入量，特别是更多的肉类、加工食品和零食。根据能量摄入量进行调整，较高的钠摄入量是超重或肥胖的危险因素（OR = 1.0041，IC 95% 1.0015-1.0067，p < 0.01）。结论：盐摄入量与肥胖相关；因为钠摄入量较高的人消耗更多的能量并且表现出更差的饮食习惯。此外，钠摄入量本身似乎与肥胖有关。
Introduction: Recent studies have indicated that diets rich in sodium may predispose to the development of obesity, either directly, or be associated with the consumption of foods that promote weight gain.Objetive: The aims of this study were to analyze the association between urinary sodium and the presence of excess of weight. Additionally, the study investigated the relationships between salt intake and dietary habits, as a high salt intake may be associated with inadequate eating habits and a high incidence of obesity.Methods: This study involved 418 adults (196 men and 222 women) aged 18 to 60 years old. Weight, height and waist circumference were measured, and we calculated, BMI and waist/height ratio. Dietary intake was estimated using a "24 h recalls", for two consecutive days, and sodium content was determined from 24 h urine sample.Results: The 34.4% of the population had overweight and 13.6% had obesity. A positive association was seen between BMI and urinary sodium concentration. Urine sodium values were also positively associated with others adiposity indicators such as waist circumference and waist/height ratio. Body weight, BMI, waist circumference, and waist/height ratio were higher in the group of individuals with a urinary sodium excretion a >= 154 mmol/l (Percentile 50) (P50). Additionally, individuals placed in this group presented a higher caloric intake and total food intake, in particular, more meat, processed food and snacks. Adjusting by energy intake, a higher sodium intake was a risk factor of being overweight or obese (OR = 1.0041, IC 95% 1.0015-1.0067, p < 0.01).Conclusions: Salt intake was associated with obesity; since people with higher sodium intake consumed more energy and presented worse eating habits. Additionally, sodium intake itself appears to be related to obesity.
