This study investigated the phenotypic, genetic, and environmental relationships between Big Five personality traits and temperamental traits on the basis of the regulative theory of temperament (RTT) using a multitrait-multimethod twin dataset. This allowed us to test specific hypotheses of the five factor theory (FFT) and the RTT. The Big Five personality factors were measured with the Neuroticism-Extraversion-Openness Five-Factor Inventory (NEO-FFI). The six regulatory temperamental traits were captured by the Formal Characteristics of Behavior-Temperament Inventory (FCB-TI). We analyzed self-reports as well as averaged peer ratings from 737 monozygotic and 395 dizygotic twins. Results showed phenotypic links between Big Five and RTT traits that could be attributed mainly to genetic factors. Genetic influences on the variance in Big Five personality traits did not account for the vast majority of genetic variance in all temperamental traits of the RTT contradicting the hypothesis of the FFT that the Big Five exhaustively cover basic temperamental traits. In line with the RTT, the FCB-TI scales showed large genetic links to Neuroticism and Extraversion and rather small links to Openness, Agreeableness, and Conscientiousness, supporting the idea of a differentiation between regulative and integrative aspects of personality.

NC is an accurate tool for assessing overweight and obesity in males and females of different age groups and could be used to screen for excess body weight in routine medical practice or epidemiological studies. It is also believed that more studies will permit the creation of a reference dataset of NC cut-off values for world populations.

The main predictors for excess birth weight in Brazil are modifiable risk factors. The implementation of adequate nutritional status in the gestational period and even after childbirth appears to be due to the quality and frequency of the follow-up of the mothers and their children by public health agencies.

Objective: To evaluate whether there is an association between altered maternal lipid profile and the lipid profile of the newborn in a maternity hospital. Subjects and method: Cross-sectional study with 435 parturients and their respective newborns. Blood samples from the newborns were collected during delivery by venipuncture of the umbilical cord close to the placenta. Blood samples from the parturients were collected in the pre-delivery room or right after delivery. The concentrations of total cholesterol, triglycerides and HDL-c were determined by an enzymatic colorimetric method and LDL-c was calculated by the Friedewald formula. Results: There was no significant difference in mean concentrations of total cholesterol, LDL-c, HDL-c and triglycerides in neonates according to altered or non-altered maternal total cholesterol, LDL-c, HDL-c and triglycerides. Conclusions: Change in maternal lipid profile is not significantly associated with the mean concentrations of total cholesterol, LDL-c, HDL-c and triglycerides in newborns.

Objectives To study the independent effect of pre-pregnancy weight, gestational weight gain (GWG), and other important risk factors on newborn birth weight. Methods Baseline data of 435 adult women and their singletons born between January and February 2012 at a public hospital in Brazil were used. Logistic regression was applied to determine the independent importance of pre-pregnancy weight and GWG for large for gestational age (LGA) newborns. Results Among all mothers, 37.9 % were overweight and obese before pregnancy and 45.3 % experienced excessive GWG. Among the newborns, 24.4 % were classified as LGA. Univariate analysis showed an association of family income, GWG, pre-pregnancy BMI and excessive GWG with LGA newborns. Smoking before and during pregnancy was associated with a decreased likelihood of giving birth to an LGA newborn compared to mothers who did not smoke. After adjustment for confounding variables, age at birth of first child, GWG, HbA1c and pre-pregnancy weight-GWG were significant and independent determinants of giving birth to an LGA newborn. Mothers with pre-pregnancy overweight and excessive GWG were more likely to deliver an LGA newborn (OR 2.54, P < 0.05) compared to mothers who were normal weight and experienced adequate GWG. Conclusions for Practice Age at first birth of child, GWG, HbA1c and pre-pregnancy overweight combined with excessive GWG are independent determinants of LGA newborns. The results of this study suggest that both primary prevention of overweight in women of childbearing age and management of GWG may be important strategies to reduce the number of LGA newborns and, consequently, the long-term public health burden of obesity.
