Abstract：
Globally 71% of deaths are attributed to non-communicable diseases (NCD). The workplace is an opportune setting for health promotion programs and interventions that aim to prevent NCDs. However, much of the current evidence is from high-income countries.
The aim of this study was to evaluate changes in NCD risk factors, associated with the Healthy Choices at Work programme (HCWP), at a commercial power plant in South Africa.
This was a before-and-after study in a randomly selected sample of 156 employees at baseline and 137 employees at 2-years. The HCWP focused on food services, physical activity, health and wellness services and managerial support. Participants completed questionnaires on tobacco smoking, harmful alcohol use, fruit and vegetable intake, physical activity, psychosocial stress and history of NCDs. Clinical measures included blood pressure, total cholesterol, random blood glucose, body mass index, waist circumference and waist-to-hip ratio. The 10-year cardiovascular risk was calculated using a validated algorithm. Sample size calculations evaluated the power of the sample to detect meaningful changes in risk factors.
Paired data was obtained for 137 employees, the mean age was 42.7 years (SD 9.7) and 64% were male. The prevalence of sufficient fruit and vegetable intake increased from 27% to 64% (p < 0.001), those meeting physical activity guidelines increased from 44% to 65% (p < 0.001). Harmful alcohol use decreased from 21% to 5% (p = 0.001). There were clinical and statistically significant improvements in systolic and diastolic blood pressure (mean difference -10.2 mmHg (95%CI: -7.3 to -13.2); and -3.9 mmHg (95%CI: -1.8 to -5.8); p < 0.001) and total cholesterol (mean difference -0.45 mmol/l (-0.3 to -0.6)). There were no significant improvements in BMI. Psychosocial stress from relationships with colleagues, personal finances, and personal health improved significantly. The cardiovascular risk score decreased by 4.5% (> 0.05).
The HCWP was associated with clinically significant reductions in behavioural, metabolic and psychosocial risk factors for NCDs.

摘要：
全球71%的死亡归因于非传染性疾病（NCD）。工作场所是旨在预防非传染性疾病的健康促进计划和干预措施的适当场所。然而,目前的大部分证据来自高收入国家。
本研究的目的是评估非传染性疾病危险因素的变化，与工作中的健康选择计划(HCFP)相关，在南非的一家商业发电厂。
这是一项前后研究，随机选择了156名基线员工和137名2年员工。HCWP专注于食品服务，身体活动,健康和保健服务和管理支持。参与者完成了关于吸烟的问卷，有害酒精的使用，水果和蔬菜的摄入量，身体活动,社会心理压力和非传染性疾病史。临床测量包括血压,总胆固醇,随机血糖，身体质量指数,腰围和腰臀比。使用经过验证的算法计算10年心血管风险。样本量计算评估了样本检测风险因素有意义变化的能力。
获得了137名员工的配对数据，平均年龄为42.7岁(SD9.7),64%为男性.水果和蔬菜摄入充足的患病率从27%增加到64%(p<0.001),符合体力活动指南的人数从44%增加到65%(p<0.001).有害酒精使用从21％下降到5％（p=0.001）。收缩压和舒张压有临床和统计学上的显着改善（平均差异-10.2mmHg（95CI：-7.3至-13.2）；和-3.9mmHg（95CI：-1.8至-5.8）；p<0.001）和总胆固醇（平均差异-0.45mmol/l（-0.3至-0.6））。BMI没有显著改善。与同事关系带来的心理社会压力，个人理财,个人健康明显改善。心血管风险评分下降4.5%(>0.05)。
HCWP与行为的临床显着减少有关，非传染性疾病的代谢和心理社会危险因素。
