Similarly , there was no clear evidence of effect for cardiovascular risk factors , although again the number of studies reporting these was small .
There was some evidence for beneficial effects on HRQOL , dietary outcomes , and physical activity , although firm conclusions can not yet be made .
The effects on healthcare utilisation and cost-effectiveness are also inconclusive , and trials are yet to measure the impact of  Internet interventions on compliance with medication .

A Web-Based Approach to Address Cardiovascular Risks in Managers: Results of a Randomized Trial
Objectives : To examine whether a Web-based health and leadership development program— design ed specifically for managers — was associated with changes in self-reported and biometric indicators of cardiovascular disease within the context of a r and omized control trial . Methods : A total of 145 managers from 8 organizations participated in a 6-month Internet-based program or a control condition . They completed pre- and posttest assessment s that included both self-reported attitudes ( on diet , exercise , and mental health ) and biometric measures ( eg , body weight , waist circumference ) . Results : The intervention was associated with improvements in dietary attitudes , dietary self-efficacy , and exercise , and reductions in distress symptoms . Women in the program reduced their waist circumference significantly more than controls . Conclusions : The program showed promise for reducing cardiovascular disease risk factors . Similar results across diverse organizations suggest the program may be useful across industry types
