- BACKGROUND: Ethnic minorities/immigrants have differential health as compared with natives. The epidemic in child overweight/obesity (OW/OB) in Sweden is leveling oft but lower socioeconomic groups and immigrants/ethnic minorities may not have benefited equally from this trend. We investigated whether nonethnic Swedish children are at increased risk for being OW/OB and whether these associations are mediated by parental socioeconomic position (SEP) and/or early-life factors such as birth weight, maternal smoking, BMI, and breastfeeding. METHODS: Data on 10,628 singleton children (51% boys, mean age: 4.8 y, born during the period 2000-2004) residing in Uppsala were analyzed. OW/OB was computed using the International Obesity Task Force's sex- and age-specific cutoffs. The mother's nativity was used as proxy for ethnicity. Logistic regression was used to analyze ethnicity-OW/OB associations. RESULTS: Children of North African, Iranian, South American, and Turkish ethnicity had increased odds for being overweight/obese as compared with children of Swedish ethnicity (adjusted odds ratio (OR): 2.60 (95% confidence interval (CI): 1.57-4.27), 1.67 (1.03-2.72), 3.00 (1.86-4.80), and 2.90 (1.73-4.88), respectively). Finnish children had decreased odds for being overweight/obese (adjusted OR: 0.53 (0.32-0.90)). CONCLUSION: Ethnic differences in a child's risk for OW/OB exist in Sweden that cannot be explained by SEP or maternal or birth factors. As OW/OB often tracks into adulthood, more effective public health policies that intervene at an early age are needed.

- PurposePrevious studies suggest that larger birth size is associated with a higher breast cancer incidence, but studies on birth measures and mortality in breast cancer cases are scarce. This study investigates survival of women after breast cancer diagnosis (n = 437) in the Uppsala Birth Cohort born in 1915–1929.MethodsCox regression was used to analyze mortality from any cause after a breast cancer diagnosis. Birth measures including gestational age (GA), birth weight (BW), BW for GA, birth length, and ponderal index (PI) were converted to standard deviation (SD) scores, and all analyses were adjusted for age and calendar time at diagnosis. Analyses were performed with and without adjustment for other birth measures, reproductive history, and adult socioeconomic position.ResultsIn fully adjusted analyses, one SD increase in GA was associated with 17 % [95 % confidence interval (CI) 6–26 %] lower mortality and one SD increase in BW was associated with 29 % (7–56 %) higher mortality. PI showed a weaker trend in the same direction: hazard ratio = 1.16 (95 % CI 1.03–1.30).ConclusionsOur results bring in new evidence that both high GA and low BW predict a better survival in breast cancer cases. Further studies need to investigate mediation of these associations.

- Background: Infant mortality rates have fallen considerably in the past decades. However, because of sparseness of historical data, it is unclear how social differences in infant mortality have changed over time.Methods: The aim of this study was to assess the association between prenatal social determinants and infant mortality in a Swedish cohort of 13 741 singletons born between 1915 and 1929. Associations and potential mediation of these determinants through other maternal and birth factors were studied using Cox regression. Analyses were repeated for deaths within the neonatal and post-neonatal periods.Results: Mother's single marital status, high parity, low birthweight (LBW), low gestational age and male sex were associated with infant mortality in fully adjusted models, whereas the associations of maternal social class, region of residence and maternal age appeared to be largely mediated through other variables. Contrary to studies reporting a ‘LBW paradox’, no interactions between gestational age or birthweight and maternal social characteristics on infant mortality were observed in this study. High maternal age, LBW and low/high gestational age were associated with neonatal mortality, whereas single marital status, high parity, LBW, low gestational age and male sex were associated with post-neonatal mortality. An association of family social class with post-neonatal mortality was largely mediated by other maternal variables.Conclusions: Our findings of determinants of neonatal and post-neonatal mortality in 1915–1929 are strikingly consistent with results from contemporary cohorts. On the other hand, contrary to most recent findings, there is no evidence of a LBW paradox in this historical cohort.
