Dietary fibre in relation to asthma, allergic rhinitis and sensitization from childhood up to adulthood. Clin Transl Allergy 2022; 12:e12188. [PMID: 35990418 PMCID: PMC9382355 DOI: 10.1002/clt2.12188] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 07/05/2022] [Accepted: 08/04/2022] [Indexed: 12/11/2022] Open
Abstract
Background Dietary fibre may reduce the risk of allergy. Our aim was to investigate the association between fibre intake in childhood, asthma, allergic rhinitis and IgE sensitization up to adulthood. Methods The individual fibre intake of 2285 participants from the Swedish population-based birth cohort BAMSE was estimated between 98- and 107-item food frequency questionnaires at ages 8 and 16 years, respectively. At 8, 16 and 24 years, asthma and allergic rhinitis symptoms were assessed by questionnaires, and sensitization to common allergens by serum IgE. Longitudinal associations were analysed by generalized estimating equations, adjusting for potential confounders. Results An inverse overall association was indicated between fibre intake at 8 years and allergic rhinitis symptoms up to 24 years (OR per 5 g/d 0.86; 95% CI 0.77-0.96), particularly in combination with airborne (0.74; 0.62-0.89) and food (0.69; 0.54-0.88) allergen sensitization. Higher fibre intake was also associated with specific allergen sensitization, for example, birch (0.77; 0.67-0.88) and soy (0.68; 0.53-0.87). No association was observed with asthma. Regarding sources, fruit (0.79; 0.67-0.94) and other (potatoes, chips/popcorn, legumes, and nuts, 0.71; 0.50-0.99), but not cereal or vegetable fibre were associated with allergic rhinitis. In additional analyses, including long-term fibre intake at 8 and 16 years, excluding participants with food-related allergic symptoms to examine reverse causation, as well as adjusting for antioxidant intake, associations were attenuated and became non-significant. Conclusion Higher fibre intake in mid-childhood may be inversely associated with allergic rhinitis and sensitization to specific allergens up to adulthood. However, avoidance of food triggers of allergic symptoms in allergic rhinitis patients may contribute to the protective associations.

Prevalence and characteristics of atopic dermatitis among young adult females and males - report from the Swedish population-based study BAMSE. J Eur Acad Dermatol Venereol 2022; 36:698-704. [PMID: 35032357 PMCID: PMC9303811 DOI: 10.1111/jdv.17929] [Citation(s) in RCA: 20] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2021] [Revised: 11/13/2021] [Accepted: 12/07/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND There is limited knowledge regarding prevalence and characteristics of Atopic Dermatitis (AD) among young adults in the general population. OBJECTIVES To study AD among young adults in a Swedish population-based birth cohort, with a particular focus on prevalence, sex differences including risk for AD at different ages, disease course and characteristics of AD at 24 years. METHODS The BAMSE cohort includes 4,089 individuals who have been followed regularly from birth to age 24 years regarding AD and atopic diseases. For this study 3,055 individuals who answered questions regarding AD at the 24-year follow-up were included. All were invited to a clinical examination including skin examination, evaluation by Williams criteria and collection of blood for analysis of specific IgE and 2,264 individuals chose to participate. RESULTS At 24 years the 12-month prevalence of AD was 17.8% and more females than males had AD (20.5% versus 14.8%), p<0.0001. The point-prevalence of ongoing AD at clinical examination was 8.0%. AD severity as assessed by Patient-Oriented Eczema Measure (POEM) did not differ between sexes. The proportion of adult onset of AD was 16.9% (92 of 543), females 17.3% versus males 16.4%. More females than males with AD at 24 years reported disturbed sleep due to itch (26.1% versus 15.5%, p<0.003). IgE-sensitization was less common among females with AD than males with AD (61.3% versus 79.6%, p<0.0001). In addition, male sex (female sex being the reference) was associated with increased odds for AD the first year of life (OR 1.31, 95% CI; 1.10-1.56), and decreased odds of AD in adolescence and young adulthood (OR 0.66, 95% CI; 0.55-0.80). CONCLUSIONS AD is a common disease among young adults and even though more females than males have AD at 24 years, adult onset of AD seems to be equally prevalent among both sexes in young adulthood.

Fruit, vegetable and dietary antioxidant intake in school age, respiratory health up to young adulthood. Clin Exp Allergy 2021; 52:104-114. [PMID: 34549838 DOI: 10.1111/cea.14020] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 04/14/2021] [Accepted: 09/19/2021] [Indexed: 02/02/2023]
Abstract
BACKGROUND Dietary antioxidants may protect the lung against oxidative damage and prevent chronic respiratory disease. We aimed to investigate fruit, vegetable and antioxidant intake (measured as total antioxidant capacity, TAC) at age 8 years in relation to asthma and lung function up to 24 years. METHODS In this study of 2506 participants from a Swedish birth cohort, diet was assessed using food frequency questionnaires. Information on asthma was collected by questionnaires, and lung function was measured by spirometry at ages 8, 16 and 24 years. Generalized estimating equations and mixed effect models were used to assess overall, age- and sex-specific associations. RESULTS After adjustment for confounders, a higher fruit intake at age 8 years was associated with a tendency to reduced odds of prevalent asthma (T3 vs. T1, OR 0.78; 95% CI 0.60-1.01, p-trend .083), with reduced odds of incident asthma and increased odds of remittent asthma (≥median, OR 0.76; 95% CI 0.58-0.99 and OR 1.60; 95% CI 1.05-2.42, respectively) up to 24 years. Comparable, but non-significant, odds ratios were observed in analyses of long-term fruit intake (mean intake at ages 8 and 16 years). In contrast, no association was observed with vegetable intake. A higher dietary TAC (T3 vs. T1) at 8 years was associated with reduced odds of prevalent asthma (OR 0.73; 95% CI 0.58-0.93, p-trend .010) and improved lung function development (FEV1 -z +0.11; 95% CI 0.01-0.21, p-trend .036 and FVC-z +0.09; 95% CI -0.01-0.20, p-trend .072) up to 24 years. Associations were more pronounced among males, and regarding asthma, participants sensitized to aeroallergens. CONCLUSIONS Antioxidant intake in school age may improve asthma and lung function up to young adulthood. Although our results should be interpreted with caution, they emphasize the importance of following current dietary guidelines regarding consumption of antioxidant-rich foods as part of a balanced diet.
