“…The results of the generalized linear mixed model also indicated that breastfeeding was positively associated with FVC, FEV1 and PEFR which supports previous work (27). This beneficial effect could be due to the physical training of prolonged suckling at the breast that induces improvement on the mechanics of ventilation (28) or immunoactive factors present in the breast milk such as cytokines and chemokines which may reduce allergic susceptibility of the lung tissue (29); this interpretation is supported by our finding in our previous report that breastfeeding had a protective effect against wheeze and allergic rhinitis (12).…”

“…Another cohort study demonstrated that children who were breastfed for o4 months had significantly higher peak expiratory flow [5]. We previously demonstrated that breastfeeding for o4 months increases FVC in 10-yr-old children, independent of maternal asthma or allergy [14].…”

“…Lung function measurements were performed at 10 and 18 yrs of age [14,19], including FVC, forced expiratory volume in 1 s (FEV1) and FEV1/FVC ratio. Lung function measurements were performed using a Koko Spirometer and software with a portable desktop device (both PDS Instrumentation, Louisville, KY, USA), according to American Thoracic Society guidelines [20].…”

“…The socioeconomic status was represented by clusters composed of the following information: 1) the British socioeconomic classes (1-6) [21], derived from parental occupation reported at birth; 2) the number of children in the index child's bedroom (collected at 4 yrs of age); and 3) family income at 10 yrs of age. This composite variable captures the family social class across the study period [14]. Family social status cluster was categorised as lower, middle and upper class.…”

Breastfeeding has been linked with increased forced vital capacity (FVC) in children but not in older adolescents. Our aim was to investigate the effects of breastfeeding duration and infant weight gain on FVC in both developmental periods.In a birth cohort, information on breastfeeding duration was collected at 1 and 2 yrs; spirometric tests were conducted at 10 and 18 yrs. To estimate the effect of breastfeeding duration on FVC at 18 yrs of age, we used linear models; to analyse repeated FVC measurements at 10 and 18 yrs of age, we used linear mixed models. Links between breastfeeding, infant weight gain and FVC at 10 and 18 yrs of age were analysed through path analyses.Among 808 breastfed children, 49% were breastfed for o4 months. At 18 yrs of age the augmenting effect of breastfeeding on FVC was reduced with increased height. Linear mixed models identified that breastfeeding duration was associated with increased FVC. Path analysis suggested a direct effect of breastfeeding on FVC at 10 yrs of age, but an indirect effect at 18 yrs of age via FVC at 10 yrs of age. Although inversely related to breastfeeding, a higher weight gain in infants led to taller adolescents and, in turn, resulted in increased FVC.In conclusion, a longer duration of breastfeeding contributes to lung health in childhood and adolescence.

“…[10][11][12][13][14][15][16][17][18][19][20][21] However, none of these studies included detailed measures of early feeding patterns, including breastfeeding intensity (the amount of breast milk relative to all milk), use of expressed milk, patterns of introduction of food groups, and diet quality in late infancy. In addition, nearly all these studies were conducted in a country other than the United States.…”

OBJECTIVE:We describe methods used in the Year 6 Follow-Up (Y6FU) of children who participated in the Infant Feeding Practices Study II (IFPSII). This study consists of a questionnaire administered 6 years after the IFPSII to characterize the health, development, and diet quality of the children. METHODS:The Y6FU sample was a subset of those who participated in IFPSII. The IFPSII participants were drawn from a national consumer opinion panel; neither the IFPSII nor the Y6FU sample is nationally representative. The Y6FU sampling frame included all qualified participants who answered at least the first postnatal questionnaire. One questionnaire was administered by mail in 2012, and nonrespondents were contacted for a telephone interview. Survey topics included measures of health, development, diet, physical activity, screen time, and family medical history. We attempted to contact 2958 mothers and obtained completed questionnaires from 1542, a response rate of 52.1%. We conducted 2 sample evaluations, 1 comparing respondents and nonrespondents on data from IFPSII and the other comparing Y6FU respondents with 6-year-old participants in the National Survey of Children' s Health.RESULTS: Y6FU mothers are more likely to be white, married, older, and of higher education and income than both nonresponders and nationally representative mothers. Comparisons also revealed health-related differences and similarities. CONCLUSIONS:Although not nationally representative, the Y6FU provides a valuable database because of its wide coverage of diet and health issues and its unique ability to link early feeding patterns with outcomes at age 6 years.
