Researchers followed over 6,000 IVF patients through six cycles, finding live birth rates range from 65-86% for younger women and 23-42% for those aged 40+, with most births being singletons.
The US received an overall 'D' grade on the first Premature Birth Report Card, with 18 states and Puerto Rico receiving failing grades. The report highlights contributing factors and prevention opportunities, including smoking and uninsured women of childbearing age.
A new Penn State study found that a variety of recruitment strategies are used to recruit and retain older workers, including employee incentives and flexible work schedules. Employers can benefit from tapping into the experience and knowledge of baby boomers and other older workers.
Preimplantation genetic screening (PGS) does not increase ongoing pregnancy or live birth rates in women over 35 undergoing IVF. The technique's effectiveness has been called into question due to various limitations, including the potential for biopsy errors and chromosomal analysis biases.
A systematic study of China's fertility policy found that 63% of couples are limited to one child, and the policy has proven remarkably effective in reducing birth rates. The study also reveals exceptions within prefectures for certain groups, highlighting the complexity of the policy.
A study by Gibson and Mace found that villages with improved water supply in rural Ethiopia experienced a significant increase in birth rates, contradicting the expected reduction in fertility. The researchers suggest that development programs should be more comprehensive, incorporating access to contraceptives.
A study in rural Ethiopia found that a tapped water supply reduced the time spent carrying water, leading to improved child survival but also increasing birth rates and childhood malnutrition. The researchers suggest that development projects should be multisectoral to avoid long-term problems.
Researchers Bocquet-Appel and Naji found a sudden 20-30% increase in birth rates worldwide during the Neolithic period, as indicated by an abrupt change in skeletal evidence. This finding corroborates a global demographic transition, with archaeological evidence showing parallels between Europe, North Africa, and the Americas.
A Canadian paper comments on a decline in cystic fibrosis birth rates since the onset of genetic testing. The study found that newborns with cystic fibrosis had lower birth weights and were at higher risk of prematurity compared to non-affected children.
Research reveals smoking reduces live birth rates by 28% and adds a decade to reproductive age for IVF patients. Quitting smoking and losing weight can improve IVF success rates, particularly for women with unexplained subfertility.
A study by the Lister Fertility Clinic in London found that women who participated in an egg-sharing program did not have a lower chance of getting pregnant or having a live birth compared to those who didn't participate. The researchers also found no evidence of increased risk of ovarian hyperstimulation syndrome among donors.
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.
