Analys av klorparaffiner i bröstmjölk och serum
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Klorparaffiner (CP) utgör en stor grupp av polyklorerade alkaner av olika kolkedjelängder och olika kloreringsgrad; kortkedjiga (C10 – C13, SCCP), medellånga (C14 – C17, MCCP) och långa (≥C18, LCCP). CP produceras i mycket stora volymer för användning som additiv (bl.a. som mjukgörare och flamskyddsmedel) i produkter, material och varor. De är globala miljöföroreningar som förekommer i abiotisk miljö, djur och människor. Hypotesen för den studie som nu genomförts är att CP uppvisar olika ackumulationsgrad i blod (serum eller plasma) jämfört med bröstmjölk. Därför har parade prover från 25 kvinnor som donerat blod och bröstmjölk analyserats med avseenden på CP i dessa båda matriser och halterna har jämförts med halter av en PCB-markör, CB-153, samt med 4,4’-DDE. Analyserna visar signifikanta haltskillnader, på fettviktsbasis, av SCCP och MCCP i serum på 22 respektive 6.2 gånger högre koncentrationer än de som uppmätts i bröstmjölken. Data visade även förhöjda halter av såväl vSCCPs (mycket korta CP) som LCCPs i serum jämfört med bröstmjölk men skillnaden i dessa båda fall är inte signifikant säkerställd. Medianhalterna av SCCP, MCCP och LCCP i serum respektive bröstmjölk är: 790, 520 och 16 ng/g fett respektive 36, 63 och 6,0 ng/g fett. 4,4’-DDE och CB-153 är jämförbara i de båda matriserna och ligger på 17 respektive 12 ng/g fett. SCCP är klassificerad som en POP i Stockholmskonventionen men inte MCCP trots höga halter i serum. CP är, oavsett kolkedjelängd, persistenta.

Ingår i: Nestle Nutr Workshop Ser Pediatr Program.. ; 60, s. 107-21

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Cereals are the most common complementary foods all over the world and there is now a novel possibility to add functional components to target health problems that are not caused by a simple nutritional deficiency. So far there have been very few published trials on the addition of functional components to infant cereals. A single trial has suggested that infant cereals containing a combination of probiotics, prebiotics and zinc are an effective adjunct to oral rehydration solution in the treatment of acute gastroenteritis. Up to now there has been no evidence that infant cereals supplemented with probiotics or prebiotics have a preventive effect on diarrhea but a recent study has suggested that a milk fat globule membrane (MFGM) protein fraction added to an infant cereal reduces the risk of diarrhea in a developing country. There are some promising results suggesting that infant cereals supplemented with probiotics or prebiotics may prevent atopic eczema. The addition of prebiotic oligosaccharides to infant cereals may lead to softer stools, likely to benefit those infants who are suffering from constipation. More studies are needed to verify these results and to assess the effects of other functional components - especially probiotics, prebiotics, nucleotides, novel protein fractions and recombinant human milk proteins - added to infant cereals.

Tidskriftsartikel (refereegranskat)abstract
- Consumption of acidic fruit pouches in infancy may damage the epithelial barrier in the gastrointestinal tract and is suggested to increase allergy risk. We aimed to explore if a high fruit pouch consumption is associated with a higher incidence of early allergic manifestations. We included 2959 parent–child dyads from the Swedish prospective, population-based NorthPop birth cohort study with parentally reported data on frequency of fruit pouch consumption at 9 months of age, as well as parentally reported eczema, wheeze, physician-diagnosed asthma, and food allergy in the first 18 months of life. Immunoglobulin E levels (IgE) in serum (n = 1792), as response to a food mix and an inhalant mix, were determined at age 18 months. Compared with no consumption, daily consumption of one or more pouches at 9 months of age was associated with inhalant sensitization (odds ratio (OR) 2.27, 95% confidence interval (CI) 1.06–4.87, n = 1792) but did not remain significant in the multivariable adjusted model (aOR 2.08, 95% CI 0.95–4.53, n = 1679). There were no associations between fruit pouch consumption and allergic manifestations at this young age. This study suggests that fruit pouch consumption is not associated with allergic phenotypes or IgE sensitization in early childhood.

Tidskriftsartikel (refereegranskat)abstract
- Background: Early life antibiotic treatment is one likely exposure influencing allergy risk. The objective was to investigate associations between pre- and postnatal antibiotic exposures and the development of allergic manifestations until age 18 months.Methods: We included 1387 mother–child dyads from the prospective, population-based NorthPop birth cohort study. Data on antibiotic exposures in pregnancy and childhood were collected by web-based questionnaires. Until the child turned 18 months old, parents (n = 1219) reported symptoms of wheeze, eczema, and physician-diagnosed asthma; parents (n = 1025) reported physician-diagnosed food allergy. At age 18 months, serum immunoglobulin E levels to inhalant (Phadiatop) and food (Food mix fx5) allergens were determined. Associations were estimated using bivariable and multivariable logistic regressions.Results: Prenatal antibiotic exposure was positively associated with food sensitization in the crude (OR 1.82, 95% CI 1.01–3.26) but not in the adjusted analyses (aOR 1.58, 0.82–3.05). A borderline significant association was found between prenatal exposure and wheeze (aOR 1.56, 0.95–2.57). Postnatal antibiotics were positively associated with wheeze (aOR 2.14, 1.47–3.11), asthma (aOR 2.35, 1.32–4.19), and eczema (aOR 1.49, 1.07–2.06). Postnatal antibiotics were negatively associated with food sensitization (aOR 0.46, 95% CI 0.25–0.83) but not with food allergy nor sensitization to inhalants.Conclusion: Pre- and postnatal antibiotic exposure demonstrated positive associations with allergic manifestations and the former also with food sensitization. In contrast, there was a negative association between postnatal antibiotics and food sensitization. Food sensitization is often transient but may precede respiratory allergies. Future studies should investigate the relationship between antibiotic exposure and food sensitization later in childhood.

Genetic preference for sweet taste in mothers associates with mother-child preference and intake
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Taste perception is a well-documented driving force in food selection, with variations in, e.g., taste receptor encoding and glucose transporter genes conferring differences in taste sensitivity and food intake. We explored the impact of maternal innate driving forces on sweet taste preference and intake and assessed whether their children differed in their intake of sweet foods or traits related to sweet intake. A total of 133 single nucleotide polymorphisms (SNPs) in genes reported to associate with eating preferences were sequenced from saliva-DNA from 187 mother-and-child pairs. Preference and intake of sweet-, bitter-, sour-, and umami-tasting foods were estimated from questionnaires. A total of 32 SNP variants associated with a preference for sweet taste or intake at a p-value < 0.05 in additive, dominant major, or dominant minor allele models, with two passing corrections for multiple testing (q < 0.05). These were rs7513755 in the TAS1R2 gene and rs34162196 in the OR10G3 gene. Having the T allele of rs34162196 was associated with higher sweet intake in mothers and their children, along with a higher BMI in mothers. Having the G allele of rs7513755 was associated with a higher preference for sweets in the mothers. The rs34162196 might be a candidate for a genetic score for sweet intake to complement self-reported intakes.

Fruit pouch consumption and dietary patterns related to BMIz at 18 months of age
- 2021
-

Tidskriftsartikel (refereegranskat)abstract
- Concerns have been raised that an overconsumption of baby food fruit pouches among toddlers might increase the risk of childhood obesity. This study aimed to quantify the consumption of fruit pouches and other fruit containing food products and to explore potential correlations between the consumption of these products and body-mass index z-score (BMIz) at 18 months, taking other predictive factors into consideration. The study was based on 1499 children and one-month-recall food frequency questionnaires from the Swedish population-based birth cohort NorthPop. Anthropometric outcome data were retrieved from child health care records. BMIz at 18 months of age was correlated to maternal BMI and gestational weight gain and inversely correlated to fruit juice consumption and breastfeeding. BMIz at 18 months of age was not correlated to consumption of fruit pouches, sugar-sweetened beverages, whole fruit or milk cereal drink. Overweight at 18 months of age was correlated to maternal BMI and inversely correlated to breastfeeding duration. To our knowledge, this is the first study that investigates possible associations between baby food fruit pouch consumption and overweight in toddlers. We found that moderate fruit pouch consumption is not associated with excess weight at 18 months of age.

Physical activity and sedentary time during pregnancy and associations with maternal and fetal health outcomes : an epidemiological study
- 2021
-
Ingår i: BMC Pregnancy and Childbirth. - : BioMed Central (BMC). - 1471-2393 .- 1471-2393. ; 21:1
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Physical activity is generally considered safe for the pregnant woman as well as for her fetus. In Sweden, pregnant women without contraindications are recommended to engage in physical activity for at least 30 min per day most days of the week. Physical activity during pregnancy has been associated with decreased risks of adverse health outcomes for the pregnant woman and her offspring. However, there are at present no recommendations regarding sedentary behavior during pregnancy. The aim was to examine the level of physical activity and sedentary time in a representative sample of the pregnant population in Sweden, and to explore potential effects on gestational age, gestational weight gain, birth weight of the child, mode of delivery, blood loss during delivery/postpartum, self-rated health during pregnancy and risk of pregnancy-induced hypertension and preeclampsia.METHODS: This was an epidemiological study using data from the prospective, population-based NorthPop study in Northern Sweden and information on pregnancy outcomes from the national Swedish Pregnancy Register (SPR). A questionnaire regarding physical activity and sedentary time during pregnancy was answered by 2203 pregnant women. Possible differences between categories were analyzed using one-way Analysis of variance and Pearson's Chi-square test. Associations between the level of physical activity/sedentary time and outcome variables were analyzed with univariable and multivariable logistic regression and linear regression.RESULTS: Only 27.3% of the included participants reported that they reached the recommended level of physical activity. A higher level of physical activity was associated with a reduced risk of emergency caesarean section, lower gestational weight gain, more favorable self-rated health during pregnancy, and a decreased risk of exceeding the Institute of Medicine's recommendations regarding gestational weight gain. Higher sedentary time was associated with a non-favorable self-rated health during pregnancy.CONCLUSIONS: Our study showed that only a minority of pregnant women achieved the recommended level of physical activity, and that higher physical activity and lower sedentary time were associated with improved health outcomes. Encouraging pregnant women to increase their physical activity and decrease their sedentary time, may be important factors to improve maternal and fetal/child health outcomes.

Symptoms and management of cow's milk allergy : perception and evidence
- 2024
-
Ingår i: Frontiers in Allergy. - : Frontiers Media S.A.. - 2673-6101. ; 5
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction: The diagnosis and management of cow's milk allergy (CMA) is a topic of debate and controversy. Our aim was to compare the opinions of expert groups from the Middle East (n = 14) and the European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) (n = 13).Methods: These Expert groups voted on statements that were developed by the ESPGHAN group and published in a recent position paper. The voting outcome was compared.Results: Overall, there was consensus amongst both groups of experts. Experts agreed that symptoms of crying, irritability and colic, as single manifestation, are not suggestive of CMA. They agreed that amino-acid based formula (AAF) should be reserved for severe cases (e.g., malnutrition and anaphylaxis) and that there is insufficient evidence to recommend a step-down approach. There was no unanimous consensus on the statement that a cow's milk based extensively hydrolysed formula (eHF) should be the first choice as a diagnostic elimination diet in mild/moderate cases. Although the statements regarding the role for hydrolysed rice formula as a diagnostic and therapeutic elimination diet were accepted, 3/27 disagreed. The votes regarding soy formula highlight the differences in opinion in the role of soy protein in CMA dietary treatment. Generally, soy-based formula is seldom available in the Middle-East region. All ESPGHAN experts agreed that there is insufficient evidence that the addition of probiotics, prebiotics and synbiotics increase the efficacy of elimination diets regarding CMA symptoms (despite other benefits such as decrease of infections and antibiotic intake), whereas 3/14 of the Middle East group thought there was sufficient evidence.Discussion: Differences in voting are related to geographical, cultural and other conditions, such as cost and availability. This emphasizes the need to develop region-specific guidelines considering social and cultural conditions, and to perform further research in this area.
