“…Additionally, the control group received a PA intervention (Jago et al, 2006) which could have increased their desire to make healthier dietary choices. However, there was no covariability of changed diet and PA behaviors in this or an earlier study (Thompson et al, 2004). It is possible that outliers could have influenced LV consumption results.…”

“…There are a few studies assessing the association between dietary behaviours and PA using objective PA data ( 11 , 29 ) , but, to our knowledge, this is the first study examining the association between breakfast frequency and objectively measuring PA in adolescents. Two previous studies using objective monitoring to assess PA and diet have shown conflicting results, with one showing that PA and fat consumption were inversely related ( 29 ) and the other indicating no relationship between change in diet or PA ( 11 ) .…”

Breakfast consumption and physical activity in British adolescents

Studies show an inverse relationship between breakfast frequency and weight gain. This may reflect poor eating habits generally and associated low physical activity (PA) or direct impacts of breakfast on mechanisms leading to lethargy and reduced PA. The relationship between breakfast frequency and PA is inconclusive. We aimed to determine whether breakfast frequency is associated with PA levels in British adolescents independent of body composition and socio-economic status (SES). Habitual breakfast frequency (self-report questionnaire) was assessed in 877 adolescents (43 % male, age 14·5 (SD 0·5) years old). PA was measured over 5 d (accelerometry, average counts/ min; cpm). Associations between daily PA and breakfast frequency were assessed using linear regression adjusted for body fat percentage and SES. Effect modification by sex and associations with PA during the morning (06.00 -12.00 hours) were explored. For boys, there were no significant associations between breakfast frequency and PA. For girls, less frequent breakfast consumption was significantly associated with lower PA (cpm) during the morning (occasional v. frequent b 2 6·1 (95 % CI 2 11·1, 2 1·1), P¼ 0·017) when adjusted for body fat percentage and SES. There were no associations between PA and breakfast consumption over the whole day; however, for girls, less frequent breakfast consumption may be associated with lower PA levels during the morning, suggesting that breakfast consumption should perhaps be taken into consideration when aiming to promote PA in adolescent girls.

“…The exclusion criteria in this study are routinely used in similar studies (31, 32); however, approximately 2% of children had WHZ >3.5 SD and were, therefore, excluded from the analysis. While measurements outside this range are typically errors, it is possible that children who were grossly overweight were excluded unnecessarily.…”

STANOJEVIC, SANJA, JULIANA KAIN, AND RICARDO UAUY. The association between changes in height and obesity in Chilean preschool children: 1996. Obesity. 200715:1012-1022. Objectives: To establish the association between changes in height and prevalence of obesity between 1996 and 2004 in Chilean preschool children. Research Methods and Procedures: Children registered in the Junta Nacional de Jardines Infantiles (JUNJI) preschool program were routinely measured three times a year and in consecutive years. Two indices [weight-for-height z-scores (WHZ) and BMI centiles] were used to define obesity. Height-for-age z-scores (HAZ) were used to define stature. Generalized estimating equations were used to describe the relationship between stature and obesity while controlling for repeated measurements in children. Results: The prevalence of obesity in Chilean preschool children has remained relatively constant over the past 9 years when either index is used. The prevalence of stunted (HAZ Յ2) children has decreased, while the proportion of children who are tall (HAZ Ͼ2) has increased. Using WHZ to define obesity, stunted children do not seem to be at increased risk of obesity when compared with children of normal height. Tall children were strongly protected from obesity when either criterion was used to define obesity. Discussion: The lack of association between stunting and obesity using WHZ Ն2 likely reflects the fact that Chile is in the post-transitional phase of the nutrition transition, and stunting is no longer a risk factor for obesity; however, the associations observed between stunting and BMI suggest that either WHZ or BMI, or both, are inaccurate criteria to define overweight. Conclusions: There is a unique relationship between stature and obesity in preschool children that is different from that observed in older children in the same population.
