Temperature during pregnancy influences the fetal growth and birth size
BACKGROUND Birth weight and length have seasonal fluctuations. However, it is uncertain which meteorological element has an effect on birth outcomes and which timing of pregnancy would explain such effect. Therefore, the purpose of this study was to examine temperature effects during pregnancy and which timing of pregnancy has effects on size at birth. METHODS A large, randomized, controlled ...
متن کاملMaternal and fetal influences on blood pressure.
To study maternal and fetal influences on blood pressure in childhood 405 children aged 4 years who were born and still resident in the Salisbury health district were visited at home for blood pressure and growth measurements. Information on the pregnancy, delivery, and baby was abstracted from the routine obstetric notes. Similar to recent findings in adults, the child's systolic pressure was ...
متن کاملDemographic Influences on Economic Growth, 1968-83
This paper describes an econometric investigation of the effects of population growth on the growth of output. A structural model yields an equation expressing output growth as a function of both demographic and nondemographic variables. This equation is estimated from data on 142 six-year growth periods in 85 countries at all levels of per capita output. Higher fertility is found to lower outp...
متن کاملEarly influences of nutrition on postnatal growth.
Health and nutrition modulate postnatal growth. The availability of amino acids and energy, and insulin and insulin-like growth factor-I (IGF-I) regulates early growth through the mTOR pathway. Amino acids and glucose also stimulate the secretion of IGF-I and insulin. Postnatal growth induces lasting, programming effects on later body size and adiposity in animals and in human observational stu...
متن کاملInfluences of thermal environment on fish growth
Thermoregulation in ectothermic animals is influenced by the ability to effectively respond to thermal variations. While it is known that ectotherms are affected by thermal changes, it remains unknown whether physiological and/or metabolic traits are impacted by modifications to the thermal environment. Our research provides key evidence that fish ectotherms are highly influenced by thermal var...
