RESUMO
AIMS AND OBJECTIVES: To increase clinical interventions to reduce modifiable risk factors for noncommunicable disease in low- and middle-income countries. BACKGROUND: Noncommunicable disease is the leading cause of death in the world and is common in low- and middle-income countries. Risk factors for noncommunicable disease are modifiable and health professionals are in an unique position to intervene and influence them. DESIGN: Clinical interventions were used as part of the Community Interventions for Health programme, a nonrandomised, controlled study undertaken in three communities - one each in China, India and Mexico. METHODS: All clinicians in intervention and control areas of the study were invited to complete surveys. A total of 2280 completed surveys at baseline and 2501 at follow-up. Culturally appropriate interventions to reduce tobacco use, improve dietary intake and increase physical activity were delivered in the intervention areas. RESULTS: Clinicians in the intervention group felt more prepared to advise smoking cessation and improvement of diet. They were more likely to test serum cholesterol and blood pressure, but less likely to take measurements of height, hip, waist and skin-fold thickness. There were more resources available to clinicians in the intervention group and they used counselling more and complementary medicine less than those in the control group. CONCLUSIONS: Community interventions which have been shown to have a positive effect in the community and workplace also change clinical practice. RELEVANCE TO CLINICAL PRACTICE: Community interventions make clinicians, including nurses, more likely to feel prepared to offer advice and more likely to use counselling. This would be expected to reduce risk factors in patients.

BACKGROUND: Non-communicable disease (NCD) is increasing rapidly in low and middle-income countries (LMIC), and is associated with tobacco use, unhealthy diet and physical inactivity. There is little evidence for up-scaled interventions at the population level to reduce risk in LMIC. METHODS: The Community Interventions for Health (CIH) program was a population-scale community intervention study with comparator population group undertaken in communities in China, India, and Mexico, each with populations between 150,000-250,000. Culturally appropriate interventions were delivered over 18-24 months. Two independent cross-sectional surveys of a stratified sample of adults aged 18-64 years were conducted at baseline and follow-up. RESULTS: A total of 6,194 adults completed surveys at baseline, and 6,022 at follow-up. The proportion meeting physical activity recommendations decreased significantly in the control group (C) (44.1 to 30.2%), but not in the intervention group (I) (38.0 to 36.1%), p<0.001. Those eating ≥ 5 portions of fruit and vegetables daily decreased significantly in C (19.2 to 17.2%), but did not change in I (20.0 to 19.6%,), p=0.013. The proportion adding salt to food was unchanged in C (24.9 to 25.3%) and decreased in I (25.9 to 19.6%), p<0.001. Prevalence of obesity increased in C (8.3 to 11.2%), with no change in I (8.6 to 9.7%,) p=0.092. Concerning tobacco, for men the difference-in-difference analysis showed that the reduction in use was significantly greater in I compared to C (p=0.014). CONCLUSIONS: Up-scaling known health promoting interventions designed to reduce the incidence of NCD in whole communities in LMIC is feasible, and has measurable beneficial outcomes on risk factors for NCD, namely tobacco use, diet, and physical inactivity.

OBJECTIVE: To reduce risk factors in workplace settings in low- and middle-income countries. DESIGN AND SAMPLE: Workplace interventions were utilized as part of the Community Interventions for Health program, a nonrandomized, controlled study undertaken in three communities in China, India, and Mexico. Exactly, 45 industrial, 82 health and 101 school workplace settings with a target population of 15,726. Two independent cross-sectional surveys of workers were conducted at baseline and follow-up, after 18-24 months of intervention activities. MEASURES: Culturally appropriate interventions to reduce tobacco use, increase physical activity, and improve dietary intake were delivered in the intervention areas. RESULTS: Exactly, 12,136 adults completed surveys at baseline, and 9,786 at follow-up. In the intervention group, the prevalence of tobacco use reduced significantly in men (-6.0%, p < .001) and the proportion eating five portions of fruit and vegetables daily increased (+6.9%, p < .001) compared with the control group. There were no significant differences between the groups for changes in physical activity or prevalence of overweight. CONCLUSIONS: Workplace interventions improved risk factors in China, India, and Mexico.

BACKGROUND: Hypertension is a significant risk factor for cardiovascular disease, and epidemiological evidence suggests that it is increasing in parallel with obesity in children and adolescents in low- and middle-income countries. AIM: To identify and determine the relationship between overweight, obesity and hypertension in a community sample of school children. METHODS: Anthropometric data were collected from 12,730 school children aged 12-18 years in China, India and Mexico as part of the Community Interventions for Health programme, an international study evaluating community interventions to reduce non-communicable disease by addressing the three main risk factors of tobacco use, unhealthy diets and physical inactivity. Logistic regression was used to examine the association of body mass index and gender and hypertension. RESULTS: Prevalence rates of hypertension were 5.2% in China, 10.1% in India and 14.1% in Mexico, and pre-hypertension rates in China, India and Mexico were 13.4%, 9.4% and 11.2%, respectively. Overweight and obesity prevalence rates varied by country and were 16.6% in China, 4.1% in India and 37.1% in Mexico. In all countries there was a significant association between overweight and obesity and rates of hypertension. Overweight children were 1.7-2.3 times more likely to be hypertensive and obese children 3.5-5.5 more likely to show hypertension than those of normal weight. CONCLUSIONS: Rates of hypertension and overweight and obesity are high in school children in China, India and Mexico, and increased bodyweight is a significant risk factor for hypertension.
