A Mayo Clinic study of 96 women found that embryo quality is key to successful pregnancies, regardless of body mass. The research suggests that uterine function is not the cause of lower birth rates among overweight women using fertility technologies.
Reproductive rates in humans are linked to metabolic energy expenditure and body mass, with women in wealthy nations experiencing low birth rates due to high caloric intake. This relationship highlights the importance of considering biological scaling laws when understanding human reproductive patterns.
A study found that young women who received the intervention had a lower pregnancy rate (38% vs. 56%) and birth rate (23% vs. 40%) by age 21, compared to those not in the program. The intervention focused on impulse control, classroom management, and family skills without sex education.
A study published in Health Education & Behavior found that community programs aimed at preventing teen pregnancy can reduce birth rates. The implementation of these programs led to a 15% decrease in birth rate in one area, while the other saw a slight increase.
Falling fertility rates in sub-Saharan Africa may signal the first steps towards a balanced population, adequate food supplies, and relative economic stability. The region's population is expected to increase from 650 million to 1.5-2 billion by 2050.
A study by Cincinnati Children's Hospital Medical Center found that early discharge for full-term, Medicaid newborns in Ohio did not result in increased rehospitalization rates. In fact, rehospitalizations decreased 23% due to better post-discharge coordination of care.
The California sea otter population has declined by 1.14% since the 1998 spring survey, with a disconcerting decline in independent adults, indicating a need for further investigation into the cause of this trend. The USGS is working to gather more information on disease, contaminants, starvation, and entanglement as contributing factors.
The US has achieved an all-time high in life expectancy, with a decline in infant mortality rates and teen pregnancy. Despite progress, there are still areas that require further improvement, such as preventable fatal injuries to children and low-birth-weight rates.
Rapid population growth is projected for Africa, Asia, and Latin America due to high fertility rates and declining mortality rates. In contrast, developed countries like Europe, North America, and Japan face below-replacement levels of fertility, but may experience modest increases in population.
Infant mortality rates have declined significantly in Latin America and the Caribbean, with infant deaths falling from 59 per 1,000 in the early 1980s to 35 per 1,000. Life expectancy has also increased, rising from 68.7 years to 71.1 years.
Researchers found that restrictive policies, such as Medicaid funding limits and 24-hour waiting periods, significantly reduced access to abortion services, leading to a decline in abortion rates. Meanwhile, increased birthrates were observed in regions with limited access to reproductive health services.
