Socioeconomic position and the risk of preterm birth--a study within the Danish National Birth Cohort.

BACKGROUND: Low socioeconomic position is generally associated with increased risk of preterm birth, but it remains unclear whether the inequality depends on the socioeconomic measure used, if the associations differ according to the degree of prematurity, and how individual level risk factors mediate the association. METHODS: The hazard ratios (HR) of preterm birth associated with five different measures of socioeconomic position and three degrees of preterm birth were analysed in a dataset of 75 890 singleton pregnancies (1996-2002) from the Danish National Birth Cohort. This, and the mediating role of selected individual level risk factors (smoking, alcohol consumption, binge drinking, pre-pregnancy body mass index, gestational weight gain) were estimated, using Cox regression analyses. RESULTS: Mothers with <10 years of education had an elevated risk of preterm birth compared with mothers with >12 years of education and the association interacted with parity, while income and occupation affected the risk to a lesser degree. The adjusted HR for less educated nulliparous and parous women were 1.22 (95% CI 1.04-1.42) and 1.56 (95% CI 1.31-1.87), respectively, compared with women with >12 years of education. For parous women with <10 years of education inclusion of smoking in the model decreased the HR of preterm birth to 1.43 (95% CI 1.19-1.72). CONCLUSIONS: Maternal educational level was the strongest predictor of preterm birth among five socioeconomic measures and the gradient did not differ significantly according to the degree of preterm birth. For parous women smoking explained some of the educational gradient but in general the selected risk factors only reduced the relative educational gradient in preterm birth marginally.

Time trends in heavy drinking among middle-aged and older adults in Denmark.

BACKGROUND: Studies have indicated an increasing proportion of heavy drinking among middle-aged and older Danes. Trends in consumption are often extremely sensitive to influence from various components of the time trends but only few have explored the age, period and cohort-related influences on late life alcohol consumption. By using age, period, and cohort modeling this study explores the time trends in heavy drinking. METHODS: Data derive from five National Health and Morbidity Surveys conducted by the Danish National Institute of Public Health in 1987, 1994, 2000, 2003, and 2005. A total of 15,144 randomly selected Danes between the age of 50 and 74 were interviewed about their alcohol intake on the last weekday and their alcohol intake in the last week. By applying the age-period-cohort model the probability of heavy alcohol drinking is estimated to separate the influence of age, period (calendar time) and cohort (year of birth). RESULTS: The unadjusted probability of heavy drinking declines by age and increases by calendar year and year of birth for both men and women. However, the negative effect of age is attenuated for women when adjusted for birth cohort, indicating that the proportion of heavy drinking women increases in younger birth cohorts. This trend is not observed for men as their drinking pattern mainly increase slightly by calendar year. CONCLUSIONS: Our Danish observations for older aged individuals correspond to the social and cultural changes in the 1960s and 1970s that possibly have affected the drinking behavior of the cohorts. Time trend analyses, such as this may serve as an excellent opportunity to extrapolate and forecast alcohol mortality and morbidity.

Improving family and community health in eastern Europe--the lifecycle approach at WHO.

There are great differences in the health status of young children in the European Region. Central Asia and the Caucasus are the worst-off areas. After reviewing under-five mortality in the eight countries of this part of Eastern Europe, a new WHO strategy to improve child survival is presented. Adopted in late 2005, the strategy has four main principles: a lifecycle approach, youth participation, equity and intersectoral collaboration.

[Alcohol consumption by middle-aged and elderly Danes from 1987 to 2003]. / Midaldrende og aeldre danskeres alkoholforbrug fra 1987 til 2003.

INTRODUCTION: The trend in alcohol consumption by middle-aged and elderly Danes has received little attention, but earlier studies indicated increased consumption. Social factors may influence the trend. Our objective was to investigate the trend in alcohol consumption by the middle-aged and elderly and inquire about significant trends among specific social subgroups. MATERIALS AND METHODS: In the Danish Health and Morbidity Survey carried out in 1987, 1994, 2000 and 2003, a total of 11,754 people aged 50 and older were asked about their alcohol consumption. The mean alcohol intake and the number of heavy drinkers were compared from year to year. RESULTS: The mean intake per day increased from 1.5 drinks in 1987 to 2.1 drinks in 2003 for men and from 0.5 drink in 1987 to 1.0 drink in 2003 for women. The percentage of elderly drinking above the sensible drinking limits increased from 15.2% to 20.4% for men and from 10.7% to 13.6% for women. The strongest increasing trend in the number of heavy drinkers was in the lowest socio-economic groups and among those married or cohabiting. CONCLUSION: The increased number of heavy drinkers among the middle-aged and elderly is of great importance to their general state of health. The increase has possibly been caused by a social and cultural development which has led to a generation of elderly who used to drink alcohol earlier in their lives and continue drinking in old age. More focus on alcohol consumption among the middle-aged and elderly in health policy initiatives is needed.
