The overall quality of evidence based on GRADE criteria was moderate for systolic blood pressure , but low for diastolic blood pressure .
INTERPRETATION Task-sharing interventions are effective in reducing blood pressure .
BACKGROUND Task sharing for the management of hypertension could be useful for understaffed and re source -poor health systems .
We assessed the effectiveness of task-sharing interventions in improving blood pressure control among adults in low-income and middle-income countries .
Beneficial effects of short-term nutritional counselling at the primary health-care level among Brazilian adults.
OBJECTIVE To evaluate the impact of a low-cost nutritional intervention in changing the lifestyle of adults . DESIGN R and omised clinical trial . SETTING Primary health-care centre in São José do Rio Preto , São Paulo State , Brazil . SUBJECTS We r and omly assigned 104 adults ( 83 women and 21 men aged 30 - 65 years , body mass index 24 - 35 kg m(-2 ) , non-diabetic ) into two groups : nutrition counselling and control . Each subject in the intervention group received three individualised nutritional counselling sessions during the first 6 months aim ed at increasing intakes of fruits , vegetables and olive oil , reducing saturated fat and improving physical activity .  Body composition , biochemical indicators and lifestyle were assessed at baseline and at 6 months and 1 year in both groups . RESULTS After 6 months of follow-up , body weight , waist circumference , diastolic blood pressure , fasting blood glucose , total and low-density lipoprotein cholesterol , total and saturated fat , and dietary energy and cholesterol levels showed a more significant decrease among subjects in the intervention group than in the control group ( P < 0.05 ) . Moreover , the intervention group showed significantly greater improvement in each intervention goal , such as reduced intake of saturated fat and increased intakes of fruits , vegetables , fibre and olive oil ( P < 0.05 ) . After 12 months of follow-up , most of the outcomes were maintained . CONCLUSIONS The low-cost nutritional intervention programme improved serum lipids profile and weight control , and appeared to be feasible for use at a primary health-care centre in a developing country
