Parental readiness to implement life-style behaviour changes in relation to children's excess weight.

AIM: The aim if this study is to evaluate parental readiness to implement changes in specific life-style behaviours for preventing or reducing obesity in children. METHODS: Eighty-seven parents of overweight or obese children participated in this cross-sectional study. Parents completed a questionnaire for the assessment of their perceptions about their children's weight and their readiness to take action in general, as well as in relation to ten obesogenic life-style behaviours. The transtheoretical model with the five stages of change (precontemplation, contemplation, preparation, action and maintenance) was used for this assessment. A total readiness score was calculated for the 10 behaviours. RESULTS: A total of 4.6% of parents were in the precontemplation-contemplation stage for overall weight management. However, this percentage was greater for particular behaviours, such as allowing children to self-regulate their food intake, having family meals, reducing screen time and increasing physical activity. Child's body mass index, paternal education level and parental perception about child's excessive weight being attributed to over-consumption of sweets and salty snacks were significantly associated with total readiness score. CONCLUSIONS: The results of the present study indicate that the high readiness for general action reported by parents of overweight/obese children does not necessarily imply their readiness to engage in changes in specific life-style behaviours.

Anthropometric and Biochemical Markers as Possible Indicators of Left Ventricular Abnormal Geometric Pattern and Function Impairment in Obese Normotensive Children.

Εmerging data indicate that various effects of obesity on the cardiovascular system can be evident during childhood. The aim of this study was to detect early changes in left ventricular structure and function in obese normotensive children and explore possible associations of these changes with anthropometric and biochemical parameters. Normotensive 8-11-year-old obese and normal weight children were included in the study. They all underwent anthropometric measurements, laboratory tests, and echocardiography study by conventional and tissue Doppler to assess geometric pattern and function of left ventricle. Statistically significant differences in most anthropometric and metabolic parameters were noticed between groups. Obese children showed higher left ventricular mass index (LVMI) (40.05 ± 9.44 vs. 28.31 ± 6.22), lower E/A ratio (1.76 ± 0.33 vs. 2.08 ± 0.56), and higher E/e' (6.04 ± 1.13 vs. 5.43 ± 0.96) compared to lean peers. Waist-to-height ratio and hs-CRP correlated significantly with E/A in the obese group. Left ventricular hypertrophy was present in 47.2% of obese children and eccentric was the prominent type. Waist-to-height ratio and serum cortisol levels in plasma increased the odds of having any type of abnormal ventricular geometric pattern. Echocardiographic evaluation of left ventricle and diastolic function could be considered for obese normotensive children based on waist-to-height ratio, hs-CRP, and serum cortisol.
