Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- We aimed to determine the short- and long-term effects on growth, body composition, metabolic and inflammatory markers following supplementation with the probiotic Lactobacillus paracasei ssp. paracasei F19 (LF19) during weaning. Methods: One-hundred and seventy-nine healthy, infants in Umeå city, Västerbotten County were randomised to daily intake of cereals with (n=89) or without (n=90) LF19 108 colony-forming units from 4 to 13 months of age. Weight, length, head circumference and body composition, assessed by skinfold thickness, were examined at 4, 5.5, 6.5, 9, 12 and 13 months of age. Venous blood was drawn at 5.5 and 13 months. In all, 171 infants completed the intervention and were invited to a follow-up at 8-9 years of age between 2009 and 2011, 120 children participated. Weight, height, sagittal abdominal diameter and body composition (using Dual Energy X-ray Absorptiometry-scan) were measured. Data on weight and height at 4 years were collected from medical records. The families filled out a 4-day food record and a food frequency questionnaire, physical activity was assessed using a pedometer for 7 days. At 5.5, 13 months and 8-9 years of age we analysed the serum blood lipid profile. At 8-9 years fasting glucose, insulin, aspartate and alanine transaminases were analysed in serum. Homeostatic Model Assessment index was calculated. At follow-up serum adiponectin, high-sensitivity C-reactive protein and plasma C-peptide, ghrelin, gastric inhibitory polypeptide, glucagon-like peptide 1, glucagon, insulin, leptin, plasminogen activator inhibitor-1, resistin and visfatin were analysed. For characterisation of the plasma metabolome, a subgroup (n=40) was analysed at 5.5 and 13 months of age by gas chromatography time-of-flight mass spectrometry (GC-TOF/MS) analysis and in all (n=112) children at the follow-up using untargeted GC-GC/MS. Results: There were no differences between the LF19 and placebo group regarding body weight, length/height at any assessment from 4 months to 8-9 years of age; nor were there any differences between the groups in body composition. In the LF19 group 19 % were overweight/obese, the corresponding number was 21 % in the placebo group (p=0.78). Analysed metabolic and inflammatory markers, both during the intervention and the follow-up did not differ between the two groups. At 13 months of age lower levels of palmitic acid and palmitoleic acid (both p<0.04) and higher levels of putrescine (p<0.01) were seen in the LF19 compared to the placebo group. These differences did not persist at 8-9 years of age. At that age, we found statistically stronger models when comparing overweight/obese and normal weight children as well as in relation to sex. Conclusion: Early intervention with the probiotic LF19 at the time of weaning exerted transient effects on the metabolome. In a long-term perspective, we found neither benefit nor harm on growth, body composition, metabolic or inflammatory markers following supplementation with LF19 during weaning.

The plasma metabolome is influenced by body weight and sex already at school age

- Diet is one of the determinants of gut microbial composition. Reported changes in the biodiversity of the gut microbiota in the obese have spurred interest in gut microbiota modulation by dietary interventions. Using an untargeted metabolomics approach, we previously reported that infant cereals with the probiotic Lactobacillus paracasei ssp. paracasei F19 (LF19) fed daily from 4 to 13 months of age affected the plasma metabolome with lower levels of fatty acids associated with obesity indices compared with placebo. The study participants were invited to a follow-up study at 8-9 years of age and 120 children participated. Venous blood was drawn after overnight fasting and plasma samples were available from 112 children. Samples were analysed using GCxGC-time-of-flight/MS for characterisation of the global plasma metabolome. A combination of multivariate and univariate analysis was used to reveal differences between the LF19 and placebo group, and according to weight class and sex. The lower levels of palmitic acid and palmitoleic acid in the LF19 group during the intervention did not remain at the follow-up. Stronger models according to weight class and sex were obtained. BMI was associated with several metabolites including the branched-chain amino acids leucine and isoleucine, and the aromatic amino acids, tyrosine and phenylalanine. Collectively, feeding LF19 during weaning induced transient effects on the plasma metabolome. The disparities seen in the metabolic profile of overweight/obese young school children underscore the need for effective early preventive and treatment strategies.

Tidskriftsartikel (refereegranskat)abstract
- Swedish child health services (CHS) is a free-of-charge healthcare system that reaches almost all children under the age of 6. The aim for the CHS is to improve children's physical, psychological and social health by promoting health and development, preventing illness and detecting emerging problems early in the child's life. The services are defined in a national programme divided into three parts: universal interventions, targeted interventions and indicated interventions.The Swedish Child Health Services Register (BHVQ) is a national Quality Register developed in 2013. The register extracts data from the child's health record and automatically presents current data in real time. At present, the register includes 21 variables.We aim to describe data available in the BHVQ and the completeness of data in BHVQ across variables.Child-specific data were exported from the register, and data for children born in the regions were retrieved from Statistics Sweden to calculate coverage.The register includes over 110000 children born between 2011 and 2022 from 221 child healthcare centres in eight of Sweden's 21 regions. In seven of the eight regions, 100% of centres report data.The completeness of data differs between participating regions and birth cohorts. The average coverage for children born in 2021 is 71%.The BHVQ is a valuable resource for evaluating Child Health Services nationally, with high coverage for the youngest children. As a result of continuous improvement of the services, the possibility to follow the development of children's health in Sweden is possible through the register. When fully expanded, the register will be a natural and essential part of developing preventive services, improving healthcare for children below 6years of age and a tool for developing evidence-based child health interventions.
