Nutrition, Growth, and Metabolism
Here you will find studies about growth, nutrition and metabolic diseases in HIV-infected and HIV-exposed children, adolescents and young adults. We study the effects of HIV and anti-HIV medications on changes over time in height and weight, bone development, pre-diabetes, fats in the blood, and how the cells make energy for the body.
Physical Activity in Youth Living with or without HIV
Adults with HIV may be at higher risk of developing heart disease. Physical activity can lower the risk of this health problem.We looked at how physical activity changes as children with HIV go through adolescence.
Vitamin D Levels During Pregnancy and Growth of Babies
Researchers have found that women living with HIV may be more likely to have a baby with low birth weight or a baby with slow growth during their first few years of life. There is also growing evidence that vitamin D levels during pregnancy can affect the health of both the mother and child. In this study, we looked at vitamin D levels of pregnant women living with HIV and the growth of their babies.
High Blood Pressure, Cholesterol, and Insulin Resistance in Youth Born without HIV
We want to know if youth born without HIV to mothers living with HIV in SMARTT are at risk for metabolic outcomes. These include high blood pressure, high cholesterol, and insulin resistance. We looked at youth in SMARTT who had high weight for their height. We compared them to similar youth in the National Health and Nutrition Examination Survey (NHANES).
Starting HIV Medications During Pregnancy and Growth in Uninfected Youth at Two Years of Age
Many pregnant women living with HIV take antiretroviral medications (ARVs) during their pregnancy. They take them for their own health and to protect their babies from getting HIV. We wanted to know if ARV exposure during pregnancy could affect how youth grow in the first two years of life. We also wanted to know if the time when a mother starts taking ARVs affects how youth grow. If youth do not grow as they should they may be at greater risk for health problems when they get older.
Timing of ARVs Used During Pregnancy and Childhood Growth
In this study, we looked at whether being exposed to antiretroviral drugs in the womb may affect how an infant grows in the first two years of life.
How HIV Affects Bone Health
In this study, we studied x-rays of children in PHACS to measure their bone mineral density. We compared uninfected and infected youth born to mothers with HIV. We want to look at their bone mineral density over time to understand more about how having HIV affects bone health.
Age at Start of Puberty in Children Born with HIV
In this study, we looked at doctors' reports of infected and uninfected youth born to mothers with HIV to find out when puberty began in infected youth compared to uninfected youth. We also looked to see if there was a link between taking HIV medicines and when puberty began.
Youth with HIV and High Cholesterol
In this study, we looked at protein levels in blood vessels of infected youth born to mothers with HIV to see how much fat was in their blood. We compared results with another study looking at children without HIV (born to mothers without HIV).
Body Fat Differences in Youth with HIV and HIV Exposure
In this study, we looked at body fat differences in infected and uninfected youth born to mothers with HIV by using a body composition test called a DEXA. We also looked at factors that could cause fat gain.
How Youth with HIV Make Energy
In this study, we compared how the mitochondria (energy-making cells) work in infected and uninfected youth born to mothers with HIV. We also looked at problems with the mitochondria and factors that were associated with how well the mitochondria worked.
