Early life predictors of intelligence in young adulthood and middle age.

Background: Studies on early predictors of intelligence often focus on single or few predictors and often on childhood intelligence. This study compared the contributions of a broad selection of potential early predictors of intelligence at different adult ages.

Methods: Information on predictors was recorded prospectively in the Copenhagen Perinatal Cohort during pregnancy, at delivery, and at 1- and 3-year examinations for children born between 1959-61.

Cognitive symptoms in major depressive disorder: associations with clinical and functional outcomes in a 6-month, non-interventional, prospective study in China.

Cognitive symptoms in major depressive disorder (MDD) are common and may negatively impact clinical and functional outcomes. The Prospective Research Observation to Assess Cognition in Treated patients with MDD (PROACT) study aimed to assess the prevalence and course of cognitive symptoms, and their associations with clinical and functional outcomes during 6 months of antidepressant treatment, in a real-world setting among Chinese patients with MDD. Outpatients (n=598) aged 18-65 years with MDD and a total score ≥17 on the Hamilton Depression Rating Scale - 17 Items (HAM-D) were observed over 6 months after initiating new antidepressant monotherapy, with follow-up visits at months 1, 2, and 6.

THE EFFECT OF LOW TO MODERATE PRENATAL ALCOHOL EXPOSURE AND BINGE DRINKING EPISODES ON DRAW-A-PERSON AT AGE 5 YEARS.

This study examined the effects of maternal alcohol consumption and binge drinking during pregnancy on children's Draw-A-Person (DAP) scores. Participants were 1,533 5-year-olds from the Danish National Birth Cohort. Regression analyses revealed an adverse effect of nine or more drinks per week.

Low to Moderate Average Alcohol Consumption and Binge Drinking in Early Pregnancy: Effects on Choice Reaction Time and Information Processing Time in Five-Year-Old Children.

Background: Deficits in information processing may be a core deficit after fetal alcohol exposure. This study was designed to investigate the possible effects of weekly low to moderate maternal alcohol consumption and binge drinking episodes in early pregnancy on choice reaction time (CRT) and information processing time (IPT) in young children.

Method: Participants were sampled based on maternal alcohol consumption during pregnancy.

No association between prenatal exposure to psychotropics and intelligence at age five.

Objective: To examine associations between prenatal exposure to selective serotonin reuptake inhibitors (SSRIs)/anxiolytics and intelligence assessed with a standard clinical intelligence test at age 5 years.

Design: Longitudinal follow-up study.

Setting: Denmark, 2003-2008.

Predictors of intelligence at the age of 5: family, pregnancy and birth characteristics, postnatal influences, and postnatal growth.

Parental education and maternal intelligence are well-known predictors of child IQ. However, the literature regarding other factors that may contribute to individual differences in IQ is inconclusive. The aim of this study was to examine the contribution of a number of variables whose predictive status remain unclarified, in a sample of basically healthy children with a low rate of pre- and postnatal complications.

Effects of tobacco smoking in pregnancy on offspring intelligence at the age of 5.

The aim of the study was to examine the effects of tobacco smoking in pregnancy on children's IQ at the age of 5. A prospective follow-up study was conducted on 1,782 women, and their offspring were sampled from the Danish National Birth Cohort. At 5 years of age, the children were tested with the Wechsler Preschool and Primary Scale of Intelligence-Revised.
