RESUMO
AIMS: The aim of the present study was to analyse trends in full breastfeeding for at least 4 months across socioeconomic position in Denmark over a 17-year-long period from 2002 to 2019 using parental education as the indicator of socioeconomic position. METHODS: The study used data on full breastfeeding collected between 2002 and 2019 by community health nurses in the collaboration Child Health Database, n=143,075. Data were linked with five categories of parental education from population registers. Social inequality was calculated as both the relative (odds ratio) and absolute social inequality (slope index of inequality). A trend test was conducted to assess changes in social inequality over time. RESULTS: A social gradient in full breastfeeding was found for the entire study period. The odds ratio for not being fully breastfed for at least 4 months ranged from 3.30 (95% confidence interval 2.83-3.84) to 5.09 (95% confidence interval 4.28-6.06) during the study period for infants of parents with the lowest level of education (primary school) compared with infants of parents with the highest level of education (5+ years of university education). The slope index of inequality was between -38.86 and -48.81 during the entire study period, P=0.80. This indicated that both the relative and absolute social inequality in full breastfeeding to at least 4 months of age was unchanged in the study period from 2002 to 2019. CONCLUSIONS: This study showed a persistent relative and absolute social inequality in full breastfeeding for at least 4 months from 2002 to 2019 in Denmark.
RESUMO
PURPOSE: To examine the effect of an educational intervention on sunbed use and intentions and attitudes toward sunbed use in 14- to 18-year-olds at continuation schools. METHODS: We randomized 33 continuation schools either to receive the educational intervention (n = 16) or to be controls (n = 17). Intervention schools received an e-magazine addressing the health risks of sunbed use. Information on behavior and intentions and attitudes toward sunbed use was gathered through self-administrated questionnaires before the intervention and at 6 months as a follow-up. The effect of the intervention was examined by multilevel linear regression and logistic regression. RESULTS: Sunbed use was significantly lower at follow-up among pupils at intervention schools versus pupils at control schools (girls: odds ratio .60, 95% confidence interval .42-.86; Boys: odds ratio .58, 95% confidence interval .35-.96). The intervention had no effect on intention to use sunbeds or attitudes toward sunbed use. The analyses revealed a significant impact of school on attitudes toward sunbed; the intraclass correlation coefficient was estimated to be 6.0% and 7.8% for girls and boys, respectively. CONCLUSIONS: The findings from the present study provide new evidence of a positive effect of an educational intervention on sunbed use among pupils aged 14-18 years at continuation schools.
