Parents represent a potentially powerful intermediary in behaviour change strategies aimed at improving the lifestyle behaviours of young children. However, to fulfil this role, parents need to have the necessary knowledge and motivation to assimilate dietary guidelines. This study aimed to assess these psychosocial constructs, and subsequent parental receptiveness to nutrition education, through investigation of the barriers and benefits perceived by parents to the provision of a healthy diet and adequate exercise for their children. A qualitative methodology was employed and 41 parents took part in seven focus groups separated by socio-economic status (SES). Across the groups, a combination of reported external barriers and unconscious internal barriers, stemming from high optimistic bias, low perceived control and unrealistic health expectations, were observed. SES differences were suggested in restrictive feeding practices, the responsibility attributed to the school and in the level and format of desired nutrition education. Overall a demand for interventions focusing on behavioural techniques rather than fact transmission was uncovered, in particular the promotion of parental self-awareness to reduce negative influences within the family food environment. Providing realistic definitions of appropriate behaviour and empowering parents to tackle children's weight issues were indicated as important targets for future education programmes.
In this study, reducing health risks was not the main motivator for people deciding to lose weight. Increasing intrinsic sense of worth gained by losing weight and continued motivation appear to be related to success. The differing experiences of people undertaking each of the four diets suggest that matching diet regimen to individual is important.
ObjectiveTo investigate the effect of commercial weight loss programmes on macronutrient composition and micronutrient adequacy over a 2 month period.DesignAdults were randomly allocated to follow the Slim Fast Plan, Weight Watchers Pure Points Programme, Dr Atkins' New Diet Revolution, or Rosemary Conley's "Eat Yourself Slim" Diet & Fitness Plan.SettingA multi-centre randomised controlled trial.Subjects293 adults, mean age 40.3 years and a mean BMI 31.7 (range 27–38) were allocated to follow one of the four diets or control group. Subjects completed a 7-day food and activity diary at baseline (prior to randomisation) and after 2 months. Diet records were analysed for nutrient composition using WinDiets (research version).ResultsA significant shift in the macronutrient composition of the diet with concurrent alteration of the micronutrient profile was apparent with all diets. There was no evidence to suggest micronutrient deficiency in subjects on any of the dietary regimens. However, those sub-groups with higher needs for specific micronutrients, such as folate, iron or calcium may benefit from tailored dietary advice.ConclusionThe diets tested all resulted in considerable macronutrient change and resulted in an energy deficit indicating dietary compliance. Health professionals and those working in community and public health should be reassured of the nutritional adequacy of the diets tested.Trial Registration NumberNCT00327821
