Objective To identify predictors of postnatal catch-up growth from birth to two years and its relation to size and obesity at five years. Design Regional prospective cohort study. Setting Avon longitudinal study of pregnancy and childhood, United Kingdom. Subjects 848 full term singletons from a 10% random sample of the Avon longitudinal study of pregnancy and childhood. Main outcome measures Maternal birth weight, prepregnancy weight, pregnancy weight gain, height, smoking, and parity, and paternal height. Weight and length of infants at birth, two years, and five years expressed as standard deviation (SD) scores from the UK reference scores for 1990. Percentage fat mass and total fat mass (estimated from skinfolds) and waist circumference at five years. Results Size at birth was representative of the national reference. Overall, 30.7% (260 of 848) of infants showed a gain in SD score for weight greater than 0.67 SD scores between zero and two years, indicating clinically significant catch-up growth. These children had lower weight, length, and ponderal index at birth than other children, and were more often from primiparous pregnancies. They also had taller fathers than other children, and their mothers had lower birth weights and were more likely to smoke during pregnancy. Children who showed catch-up growth between zero and two years were heavier, taller, and fatter (body mass index, percentage body fat, and waist circumference) at five years than other children. Conclusions In this contemporary well nourished cohort, catch-up growth was predicted by factors relating to intrauterine restraint of fetal growth. Children who showed catch-up growth between zero and two years were fatter and had more central fat distribution at five years than other children. Mechanisms that signal and regulate early catch-up growth in the postnatal period may influence associations between small size at birth and risks for disease in adulthood.Papers

Picky eating (also known as fussy, faddy or choosy eating) is usually classified as part of a spectrum of feeding difficulties. It is characterised by an unwillingness to eat familiar foods or to try new foods, as well as strong food preferences. The consequences may include poor dietary variety during early childhood. This, in turn, can lead to concern about the nutrient composition of the diet and thus possible adverse health-related outcomes. There is no single widely accepted definition of picky eating, and therefore there is little consensus on an appropriate assessment measure and a wide range of estimates of prevalence. In this review we first examine common definitions of picky eating used in research studies, and identify the methods that have been used to assess picky eating. These methods include the use of subscales in validated questionnaires, such as the Children's Eating Behaviour Questionnaire and the Child Feeding Questionnaire as well as study-specific question(s). Second, we review data on the prevalence of picky eating in published studies. For comparison we present prevalence data from the UK Avon Longitudinal Study of Parents and Children (ALSPAC) in children at four time points (24, 38, 54 and 65 months of age) using a study-specific question. Finally, published data on the effects of picky eating on dietary intakes (both variety and nutrient composition) are reviewed, and the need for more health-related data and longitudinal data is discussed.
