Similar effects also appeared in SBP and DBP categories regardless of follow-up duration .
PA+D interventions had larger improvement effects on CVD risk factors than PA alone interventions .
In adults without IGT or diabetes , lifestyle interventions result ed in significant improvements in SBP , DBP , TC , LDL-C , HDL-C , and TG , and might further reduce CVD risk
Structured lifestyle interventions can reduce diabetes incidence and cardiovascular disease ( CVD ) risk among persons with impaired glucose tolerance ( IGT ) , but it is unclear whether they should be implemented among persons without IGT .
We conducted a systematic review and meta-analyses to assess the effectiveness of lifestyle interventions on CVD risk among adults without IGT or diabetes .
A clinical trial of the effects of dietary patterns on blood pressure. DASH Collaborative Research Group.
BACKGROUND It is known that obesity , sodium intake , and alcohol consumption factors influence blood pressure . In this clinical trial , Dietary Approaches to Stop Hypertension , we assessed the effects of dietary patterns on blood pressure . METHODS We enrolled 459 adults with systolic blood pressures of less than 160 mm Hg and diastolic blood pressures of 80 to 95 mm Hg . For three weeks , the subjects were fed a control diet that was low in fruits , vegetables , and dairy products , with a fat content typical of the average diet in the United States . They were then r and omly assigned to receive for eight weeks the control diet , a diet rich in fruits and vegetables , or a " combination " diet rich in fruits , vegetables , and low-fat dairy products and with reduced saturated and total fat . Sodium intake and body weight were maintained at constant levels . RESULTS At base line , the mean ( + /-SD ) systolic and diastolic blood pressures were 131.3+/-10.8 mm Hg and 84.7+/-4.7 mm Hg , respectively . The combination diet reduced systolic and diastolic blood pressure by 5.5 and 3.0 mm Hg more , respectively , than the control diet ( P<0.001 for each ) ; the fruits- and -vegetables diet reduced systolic blood pressure by 2.8 mm Hg more ( P<0.001 ) and diastolic blood pressure by 1.1 mm Hg more than the control diet ( P=0.07 ) . Among the 133 subjects with hypertension ( systolic pressure , > or = 140 mm Hg ; diastolic pressure , > or = 90 mm Hg ; or both ) , the combination diet reduced systolic and diastolic blood pressure by 11.4 and 5.5 mm Hg more , respectively , than the control diet ( P<0.001 for each ) ; among the 326 subjects without hypertension , the corresponding reductions were 3.5 mm Hg ( P<0.001 ) and 2.1 mm Hg ( P=0.003 ) . CONCLUSIONS A diet rich in fruits , vegetables , and low-fat dairy foods and with reduced saturated and total fat can substantially lower blood pressure . This diet offers an additional nutritional approach to preventing and treating hypertension
