Social cost studies report that alcohol use and misuse impose a great economic burden on society, and over half of the total economic costs are estimated to be due to the loss of work productivity. Controversy remains, however, as to the magnitude and direction of the effects of alcohol consumption on productivity. Furthermore, most of the studies have looked at the relationship between problem drinking and wages. This paper investigates the impact of problem drinking on employment by analysing a random sample of men and women of prime working age from six Southern states in the US (Alabama, Arkansas, Georgia, Louisiana, Mississippi and Tennessee). The data set contains 4898 females and 3224 males, with information on both employment and problem drinking. To eliminate the bias that may result from single-equation estimation, we used a bivariate probit model to control for possible correlation in the unobservable factors that affect both problem drinking and employment. We find no significant negative association between problem drinking and employment for both men and women, controlling for other covariates. The findings are consistent with other research and highlight several methodological issues. Furthermore, the study suggests that estimates of the costs of problem drinking may be overstated owing to misleading labour supply relationships.

This study examined prescribing practices for antipsychotic medications at 13 Veterans Affairs (VA) medical centers and whether patients' sociodemographic characteristics were associated with receiving novel agents. Automated pharmacy data were used to identify 599 patients who had been diagnosed as having schizophrenia and who had received a prescription for an antipsychotic medication after their last discharge from a VA medical center in 1997. Novel antipsychotics were found to have been prescribed for almost half of the patients (47 percent). In logistic regression analysis, significant variations in prescription of novel agents were found among the facilities and among ethnic groups. The results of this study suggest that prescribing practices are influenced by both facility and patient characteristics.

BackgroundThe quality of the family environment—in particular, the kind of parenting children receive in their early years—plays a critical role in influencing children’s growth and development. To facilitate the development and delivery of appropriate parenting and family interventions for Chinese parents, this study explores the prevalence of the difficulties that may arise in the course of child-rearing, the associated sociodemographic factors and parents’ help-seeking behavior.MethodsA cross-sectional self-reporting survey was conducted with a sample of 2229 parents of children between 6 and 35 months of age. Using a stratified random-digit design, parents from 15 Chinese cities were surveyed to determine their child-rearing difficulties, support-seeking behavior and their preferences for service delivery. The sociodemographic factors that influenced major child-rearing difficulties were analyzed using bivariate and logistic analyses.ResultsThe majority (87.5%) of Chinese parents of children aged 6–35 months reported experiencing child-rearing difficulties. Nearly one third (31.5%) of parents reported experiencing major difficulties. Feeding and sleep problems were most often reported. Regression analysis revealed that major child-rearing difficulties most often involved male children (OR = 1.35, 95% CI 1.11–1.64), single-child households (OR = 1.38, 95% CI 1.07–1.77), and households with financial problems (OR = 1.40, 95% CI 1.06–1.85). Just over one third of parents (33.44%) sought professional support, while 21.37% had attended a parenting course in the past year. Prefer ways of sourcing parental support included professional online platform (69.24%), self-help books (43.70%), face-to-face consultation (24.99%), and attending lectures (36.57%).ConclusionsChild-rearing difficulties are common among parents of children between 6 and 35 months of age in Chinese cities. The family with boys, single-child, financial problems, and father not joining in child-rearing may face the high risk to major child-rearing difficulties. The national initiative to provide more guidance and support for child-rearing difficulties is worthwhile, as is the development of online parenting programs.

Abstract

The objectives of this longitudinal study were to examine the trajectory of breastfed infants’ growth in China to update growth standards for early childhood, and to compare these updated Chinese growth standards with the growth standards recommended by the World Health Organization (WHO) in 2006.This longitudinal cohort study enrolled 1,840 healthy breastfed infants living in an "optimal" environment favorable to growth and followed up until one year of age from 2007 to 2010. The study subjects were recruited from 60 communities in twelve cities in China. A participating infant’s birth weight was measured within the first hour of the infant’s life, and birth length and head circumference within 24 hours after birth. Repeated weekly and monthly anthropometric measurements were also taken. Multilevel (ML) modelling via MLwiN2.25 was fitted to estimate the growth curves of weight-for-age (WFA), length-for-age (LFA), and head circumference-for-age (HFA) for the study sample as a whole and by child sex, controlling for mode of delivery, the gravidity and parity of the mother, infant’s physical measurements at birth, infant’s daily food intaking frequency per day, infant’s medical conditions, the season when the infant’s physical measurement was taken, parents’ ages, heights, and attained education, and family structure and income per month. During the first four weeks after birth, breastfed infants showed an increase in weight, length, and head circumference of 1110g, 4.9 cm, and 3.2 cm, respectively, among boys, and 980 g, 4.4 cm, and 2.8 cm, respectively, among girls. Throughout infancy, the total growth for these three was 6930 g, 26.4 cm, and 12.5 cm, respectively, among boys, and 6480 g, 25.5 cm, and 11.7 cm, respectively, among girls. As expected, there was a significant sex difference in growth during the first year. In comparison with the WHO growth standards, breastfed children in our study were heavier in weight, longer in length, and bigger in head circumference, with the exception of a few age points during the first two to four months on the upper two percentile curves.Our data suggested the growth curves for breastfed infants in China were significantly different in comparison with those based on the WHO standards. The adoption of the WHO infant growth standards among Chinese infants, as well as the methods used in the development of such growth standards in China, need careful and coordinated consideration.

Alcohol use and misuse impose economic burdens, with over half the total costs estimated associated with lost productivity. Research on labor productivity and alcohol abuse has been limited by methodologic differences, making conclusions equivocal. This study employed two waves of data from a community probability sample of 658 at-risk drinkers. It analyzed the prospective impact of several measures of drinking and drinking consequences on the 6-month follow-up probability of not being employed and fewer weeks of employment if employed. Drinking seven drinks or more on an average drinking day significantly increased the likelihood of not working and, for those who were working, reduced weeks of employment. Thus, productivity benefits may accrue from developing treatments for at-risk drinkers, particularly interventions to reduce drinking.
