ObjectivesAdherence to lifestyle interventions is crucial for the treatment of obesity. However, there is little research about adherence to lifestyle interventions in persons around retirement age. The objectives of this study are (1) to identify factors associated with the adherence to resistance training and a hypocaloric diet and (2) to describe the association between adherence and changes in body composition outcome parameters.DesignThis secondary data analysis included three randomized controlled trials.Setting & participantsThe inclusion criteria of the participants were an age of 55–75 years, a BMI ≥ 25 kg/m2 and receiving both a hypocaloric diet and resistance training. All participants were residing in the community.MeasurementsAdherence to hypocaloric diet was measured through the mean dietary intake on the basis of a 3-day dietary record. If the participant consumed at least 600 kcal less than the individual caloric requirements, they were considered adherent. Adherence to resistance training was achieved if ≥67% of the recommended training sessions were attended over the course of the study periods.Results232 participants were included, 47.0% female, mean age 64.0 (±5.5) years. 80.2% adhered to resistance training and 51.3% adhered to a hypocaloric diet. Older age (Beta 0.41; 95% CI 0.05, 0.78; p = 0.028) and male sex (Beta 7.7; 95% CI 3.6, 11; p < 0.001) were associated with higher resistance training adherence. A higher BMI at baseline (Beta 6.4; 95% CI 3.6, 9.2; p < 0.001) and male sex (Beta 65; 95% CI 41, 88; p < 0.001) were associated with higher adherence to hypocaloric diet.ConclusionWe identified several associated factors (sex, age and BMI at baseline) that should be considered to promote adherence in future lifestyle intervention studies in persons around retirement age. We recommend including behavior change techniques in lifestyle interventions and consider sex-specific interventions to improve the adherence of women.

The traditional paternalistic approach in health care is increasingly developing towards a patient-centered care (PCC) approach. However, not all patients are able to take advantage of the positive effects of PCC. Inadequate health literacy (HL) is an important limiting factor in the ability of patients to take on an active role and exchange information with their health care provider effectively. A provenly effective approach to improvement of provider-patient interaction and health outcomes is the use of health-related questionnaires. The aim of the research project described within this thesis was to adapt the most frequently-used questionnaire in Dutch physical therapy practice and add information and communication technology to it. A Dutch and Turkish version of the tool called Talking Touch Screen Questionnaire (TTSQ) was developed and evaluated on both usability and validity aspects. The current prototype of the tool does not yet fully solve the problems native and minority patients with low (health) literacy have with completing the adapted questionnaire. Big challenges in future development and testing the TTSQ are the recruitment of vulnerable members of the hard-to-reach native and minority target populations and finding research methods that suit the abilities and needs of these participants. This is expected to be a very challenging, labor- and time-consuming process. On the other hand, having a usable, valid and reliable TTSQ may well save a lot of time and money in both research and clinical practice in the future.
