ABSTRACT
The aim of this study was to determine adherence and attrition rates in a lifestyle intervention for people with metabolic syndrome. Adherence and attrition data from a randomized controlled trial were collected. Participants were classified as adherence group if they completed assessments at 3 and 6 months follow-up and as attrition group if they did not. Physical activity and quality of life was measured using the International Physical Activity Questionnaire [IPAQ] and the Short Form Health Survey [SF-36]. Generalized Estimating Equations [GEE] was used to explore predictors of attrition. The mean age of participants [n=160] was 44.1 years. Attrition rate in the intervention and control groups at first follow-up were the same [20%]. However, the control group had significantly higher attrition rate [%33.7] compared to the intervention group [%20] at 6 months follow up. Results showed that low educated participants were more likely to not stay in the study than better educated participants [OR=2.95,CI:1.39-6.33,P=0.05]. According with length of the study, attrition was decreased at six month [OR=0.66,CI:0.52-0.83,P<0.001]. Also, some aspects of health-related quality of life contributed to the attrition rate. Those who had higher scores on general health [OR=0.66,CI:0.54-0.97,P=0.023], social functioning [OR=0.44,CI:0.40-0.76,P=0.032], role emotional [OR=0.74,CI:0.54-0.98,P=0.18], vitality [OR=0.55,CI:0.38-0.90,P=0.015] and mental health [OR=0.63,CI:0.45-0.85,P=0.033] were more likely to stay in the study. It remains a concern that Web-based lifestyle programs may fail to reach those who need it most. Participant in the study generally had better quality of life than those who were lost to follow up
ABSTRACT
Lifestyle is recognized as a key factor as the cause and management of the metabolic syndrome. The aim of this study was to identify individuals at increased cardiovascular diseases risk and determine main features of lifestyle of participants with metabolic syndrome via internet. The study was conducted from Jun 22 to August 22, 2012 in Tehran, Iran. Recruitment was carried out through the study website. Participants with metabolic syndrome who were interested and met the study criteria were invited for free clinic visits and clinical assessments. Baseline measurements were metabolic syndrome risk factors. Physical activity and dietary intake were measured by international physical activity questionnaire [IPAQ- short form] and the frequency food questionnaire [FFQ] respectively. Metabolic syndrome was defined according to Adult Treatment Panel III diagnostic criteria. Mean [SD] age for men and women were 41.9 [10.4] and 48.1 [7.8] yr respectively. Men were well educated and more likely to participate in the study than women. Men with metabolic syndrome had larger waist circumference [105.5] and lower BMI [29.1] than women with metabolic syndrome [P<0.001]. Approximately 73% of the sample was inactive and 3% of participants had health enhancing physical activity. There were significant differences in the intakes of total fat and cholesterol between men and women [P<0.001]. Because of the high prevalence of metabolic syndrome, national lifestyle modification policies must be developed for population. Web-based healthy lifestyle programs may contribute to the reduction of the metabolic syndrome components
