To examine the associations among nutritional label use, medically diagnosed hypertension, and sociodemographic factors among teachers.
A cross-sectional study of elementary and secondary school teachers in Londrina, Paraná, Brazil, was conducted. Data regarding sociodemographic variables, hypertension diagnosis, and the reading of nutritional information on food/beverage labels were collected in 2012-2013. Associations were analyzed using Chi-square test or Fisher's exact test, and multivariate binary logistic regression models were used to adjust for possible confounders; odds ratios (ORs), 95% confidence intervals (CIs), and adjusted values were calculated.
Of the 978 teachers interviewed, 15% were diagnosed with hypertension, and 62.5% read nutritional information in the 12 months prior to the survey (41% frequently or always). No differences were found between teachers with and without hypertension with regard to frequent reading (frequently/always) of nutritional labels. The frequent use of nutritional labels was significantly associated with female sex (OR = 1.39; 95% CI = 1.04-1.85) and the highest monthly family income level (OR = 1.82; 95% CI = 1.07-3.11). Teachers with hypertension reported checking for sodium more frequently than those without (adjusted value = 0.040). Medical advice (adjusted value <0.001) and choosing healthier foods (adjusted value = 0.002) were the major reasons for reading labels provided by teachers with and without hypertension, respectively.
Checking for sodium values on nutritional labels was significantly higher among teachers with hypertension, which most likely results from medical advice, and was the major reported reason for reading these labels.
探讨教师群体中营养标签使用情况、医学诊断高血压与社会人口学因素之间的关联。
对巴西巴拉那州隆德里纳市的中小学教师进行了一项横断面研究。2012 - 2013年收集了有关社会人口学变量、高血压诊断以及食品/饮料标签营养信息阅读情况的数据。采用卡方检验或费舍尔精确检验分析关联，并使用多变量二元逻辑回归模型对可能的混杂因素进行调整；计算比值比（OR）、95%置信区间（CI）和调整后的 值。
在接受访谈的978名教师中，15%被诊断患有高血压，62.5%在调查前12个月阅读过营养信息（41%经常或总是阅读）。高血压教师与非高血压教师在经常阅读（经常/总是）营养标签方面未发现差异。营养标签的频繁使用与女性性别（OR = 1.39；95% CI = 1.04 - 1.85）和最高月家庭收入水平（OR = 1.82；95% CI = 1.07 - 3.11）显著相关。高血压教师报告比非高血压教师更频繁地查看钠含量（调整后 值 = 0.040）。接受医学建议（调整后 值 <0.001）和选择更健康的食物（调整后 值 = 0.002）分别是高血压教师和非高血压教师阅读标签的主要原因。
高血压教师中查看营养标签上钠含量值的比例显著更高，这很可能是医学建议的结果，也是报告的阅读这些标签的主要原因。
