OBJECTIVES We examined 2 birth cohort effects on antibiotic prescribing during the first year of life (henceforth, infancy) in Denmark: (1) the birth season effect on timing and overall occurrence of antibiotic prescribing, and (2) the birth year effect amid emerging nationwide pneumococcal vaccination programs and changing prescribing guidelines. METHODS We linked data for all live births in...
Every year, some 3.9 million girls aged 15 to 19 years undergo unsafe abortions (1). Approximately 16 million girls aged 15 to 19 years and 2.5 million girls under 16 years give birth each year in developing regions (2, 3). Complications during pregnancy and childbirth are the leading cause of death for 15 to 19 year-old girls globally (4). Adolescent mothers (ages 10 to 19 years) face higher r...
