- AIM: To investigate the development of waist circumference (WC) in preschool children born preterm compared with a population-based reference.BACKGROUND: Children born preterm are reported to be insulin resistant, despite being lean during early childhood. We hypothesize that the mechanism is through increased visceral adiposity.METHODS: Data from 4446 preschool children (2169 girls/2277 boys) born in 2001-2006 from a population-based study were compared with longitudinal measurements of body mass index (BMI) and WC from a cohort of 152 children (64 girls/88 boys) born moderately preterm in 2002-2004 (gestational age, 32-37 weeks).RESULTS: In the preterm children, the mean WC was 2.8 cm larger compared with the reference group (p < 0.001) at 2 years of age but not at 5 years of age. There was no significant difference in the mean BMI at 2 years of age. The preterm group was significantly leaner at 5 years of age, with a mean BMI of 15.13 compared with 15.98 in the reference group (p < 0.001).CONCLUSION: Children born moderately preterm present as lean during early childhood but have an increased waist circumference in infancy, pointing towards a change in fat distribution with more abdominal fat. This may have implications for their metabolic status.

- Background Family history plays a major role in the development of allergic rhinitis. External influences, such as a farm childhood and fish introduction have been suggested to play a protective role. The aim was to analyse early risk factors and protective factors for allergic rhinitis at school age. Methods The material is a prospective, longitudinal study of a cohort of children born in the region of western Sweden in 2003 where 8,176 families (50% of the birth cohort) were randomly selected. The parents answered questionnaires at 6 months, 12 months, 4½ years and 8 years of age. The response rate at eight years was 80% (4,051 of 5,044 questionnaires distributed). Results At eight years of age, 441 children (11.3%) had used medicines for allergic rhinitis the past twelve months. The mean onset age was 5.1 year and 61.9% were boys. In a multivariate analysis of factors associated with allergic rhinitis with p<0.1, we found that living on a farm at 4½ years was inversely associated with allergic rhinitis treated with medicines at 8 years (adjusted odds ratio 0.31, 95% confidence interval (0.13, 0.78)). Positive associations were seen with parental allergic rhinitis (2.73 (2.12, 3.52)), food allergy first year (2.45 (1.61, 3.73)), eczema first year (1.97 (1.50, 2.59)), neonatal antibiotics (1.75 (1.03, 2.97)) and male gender (1.35 (1.05, 1.74)). Conclusion In conclusion, we found that a family history of rhinitis, early food allergy, early eczema and male gender increased the risk of rhinitis at school age. Furthermore, we found a protective effect of living on a farm at preschool age, and that antibiotics neonatally increased the risk. Both findings are compatible with the hygiene hypothesis.

- BACKGROUND: Breastfeeding is associated with many benefits for both mother and child. Initiation rates are high in Sweden. Recently a slight decline is seen.AIM: The aim of this study was to assess factors associated with discontinuation of breastfeeding during the first 4 weeks.METHOD: A population-based longitudinal birth cohort study recruiting from 2007 to 2008 in south-western Sweden. At the first visit to the child health centre, parents were asked to complete a questionnaire. Also, the infants' height, weight, head and waist circumference were collected. Response rate was 69.2%.RESULTS: Twenty-seven per cent of mothers had breastfeeding problems. In a multivariate analysis, there was a negative correlation between breastfeeding and use of pacifier (OR 3.72; CI 2.09-6.63), maternal smoking (OR 2.09; CI 1.08-4.05) and breastfeeding problems (OR 2.54; CI 1.73-3.71). Breastfeeding problems were correlated with poor sucking technique (OR 2.96; CI 2.14-4.07), support from maternity ward (OR 2.56; CI 2.05-3.19) and perceived poor weight gain (OR 1.37; CI 1.00-1.86).CONCLUSION: Many mothers reported breastfeeding problems that are associated with an early cessation. This is preventable with support, but the timing is crucial. To promote breastfeeding, the support from the child health centres must be tailored with the maternal perspective in mind.© 2011 Foundation Acta Pædiatrica

- Background: Severe wheezing in early life is associated with an increased risk of asthma during childhood and adolescence. The aim of the present follow-up was to investigate the asthma prevalence and risk factors for asthma in adulthood. Methods: We have prospectively studied asthma development in 101 children hospitalized due to severe wheezing before the age of 24 months. The cohort was re-investigated at a mean age of 27 years and tested for bronchial hyper-responsiveness and allergic sensitization. The response rate in adulthood was 81% (82/101). The results were compared with a population-based, age-matched control group (n=1,210) recruited from the West Sweden Asthma Study. Results: Current doctor-diagnosed asthma was found in 37% (30/82) compared with 7% (82/1,210) in the control group. The risk of adult asthma in the cohort compared with the control group was increased 10-fold (adjusted OR 10.0, 95% CI 5.3-18.7), independently of allergic rhinitis, gender, smoking and heredity. Within the cohort, current allergy (aOR 9.6, 95% CI 3.0-31.2) and female gender (aOR 3.2, 95% CI 1.1-9.3) independently increased the risk of adult asthma. Females with current allergy had the highest risk of adult asthma (OR 29.4, 95% CI 5.0-173.3), compared with males without allergy. When separately adjusting for factors present at admission in early life within the cohort, a family history of asthma was a significant risk factor for asthma in adulthood (aOR 4.0, 95% CI 1.3-12.5). Conclusion: Subjects with severe early wheezing have a 10-fold increase in the risk of adult asthma compared to an age-matched control group, adjusted for allergic rhinitis, gender, smoking and heredity.

- AIM: To compare airway function in early adulthood in subjects with wheezing in infancy with age-matched controls and to analyze what accounts for a possible difference. METHODS: Asthma development has been prospectively studied in 101 children hospitalized due to wheezing before the age of two. The cohort was re-investigated at age 17-20 years and tested with spirometry and for bronchial hyper-responsiveness and allergic sensitization. An age-matched population (n = 294) was used for comparison. RESULTS: The cohort had a significantly lower FEV(1)/FVC ratio and MEF(50), both pre- and post-bronchodilation, compared with the controls, P < 0.01. The reduction in airway function was most evident in current asthmatic female subjects, but a reduced pre-bronchodilation FEV(1)/FVC ratio was also seen in symptom-free cohort subjects, P = 0.03. In the multivariate analysis, female gender was the most prominent independent risk factor for reduced airway function in early adulthood, pre-bronchodilation OR 4.0 (1.4-11.3) and post-bronchodilation OR 8.8 (1.8-42.0). In addition, a history of early wheezing, that is, belonging to the cohort, was an independent risk factor for reduced airway function pre-bronchodilation, OR 3.3 (1.3-8.7). Furthermore, there was an association between current bronchial hyper-responsiveness and an increased risk of reduced airway function post-bronchodilation, OR 7.3 (2.0-26.6). CONCLUSION: Reduced airway function in early adulthood was found in subjects with wheezing early in life, compared with age-matched controls. The reduction was most prominent in females with current asthma.

- Obesity-related adverse health consequences are closely associated with abdominal obesity. Risk factors for overweight and obesity have been studied but there is a lack of information regarding risk factors for abdominal obesity, especially in the preschool population. The aim of the present study was to examine early life risk factors for an increased waist-to-height ratio (WHtR) in children at five years of age and, in addition, to investigate if these risk factors also were associated with overweight or obesity.The study population comprised 1,540 children from a population-based longitudinal birth cohort study that included 2,666 Swedish children. The children were included if they had complete growth data for the analyses used in this study. Children were classified as having WHtR standard deviation scores (SDS) ≥ 1 or < 1 at five years of age, according to Swedish reference values, and as having body mass index standard deviation scores (BMISDS) for overweight/obesity, or normal weight/underweight according to the International Obesity Task Force criteria. Associations between child-related, socioeconomic status-related, parental health-related and nutrition- and feeding practice-related factors during the first two years and a WHtRSDS ≥ 1 or a BMISDS for overweight/obesity at five years were investigated with logistic regression analyses.At five years of age, 15% of the children had WHtRSDS ≥ 1 and 11% had overweight or obesity. In multivariable analyses, rapid weight gain (RWG) during 0-6 months (OR: 1.90, 95% CI: 1.23-2.95, p = 0.004), maternal pre-pregnancy BMI (1.06, 1.01-1.11, p = 0.019) and paternal BMI (1.11, 1.01-1.21, p = 0.028) were associated with WHtRSDS ≥ 1. RWG during 0-6 months (2.53, 1.53-4.20, p<0.001), 6-12 months (2.82, 1.37-5.79, p = 0.005), and maternal pre-pregnancy BMI (1.11, 1.06-1.17, p<0.001) were associated with overweight or obesity.Early risk factors, including rapid weight gain, are associated with increased WHtRSDS and overweight or obesity at 5 years of age. Preventive interventions should target early RWG and parental overweight and obesity.

- Inhaled corticosteroids have resulted in the improved control of asthma and a reduced need for hospitalisation. This study aimed to examine the prevalence of uncontrolled asthma and factors that affect asthma control.The data came from a longitudinal cohort study of children. The parents answered questionnaires from age 6months to 12years. The response rate at age 12years was 76% (3637/4777) and doctor-diagnosed asthma was reported in 6.4% (n=233). Asthma control was examined with the Asthma Control Test (ACT), where scores below 20 denote uncontrolled asthma.Of the children with asthma at age 12 years, 15% had an ACT value below 20, that is uncontrolled asthma. Independent risk factors for uncontrolled asthma were wheeze triggered by exercise (adjusted OR, aOR 5.6; 1.9-16.6), cat at home (aOR 3.5; 1.2-10.0) and current doctor-diagnosed rhinitis (aOR 2.8; 95% CI 1.1-7.0). A higher education in the parents reduced the risk of uncontrolled asthma (aOR 0.3; 95% CI 0.1-0.8). Only six children (i.e. 2.6%) reported hospitalisation due to asthma during the last year.Of the children with asthma, 15% had uncontrolled asthma. Higher education in the parents was associated with better asthma control in the children.
