New Data on Physical Inactivity
Briefs
A study published online by JAMA Psychiatry suggests an increased risk for first-time use of an antidepressant and a first diagnosis of depression among women in Denmark using hormonal contraception, especially adolescents. Researchers used registry data in Denmark for a study population of more than 1 million women and adolescent girls (ages 15 to 34 years). They were followed up from 2000 through 2013, with an average follow-up time of 6.4 years. During the follow-up period, 55% of the women and adolescents were current or recent users of hormonal contraception. There were 133,178 first prescriptions for antidepressants and 23,077 first diagnoses of depression during follow up. Compared with nonusers, women who used combined oral contraceptives had 1.23-times higher relative risk of a first use of an antidepressant, and the risk for women taking progestin-only pills was 1.34-fold. Estimated risks for depression diagnoses were similar or lower. The risk for women varied among different types of hormonal contraception. Some of the highest risk rates were among adolescent girls, who had 1.8-times higher risk of first use of an antidepressant using combined oral contraceptives and 2.2-times higher risk with progestin-only pills. Adolescent girls who used nonoral products had about 3-times higher risk for first use of an antidepressant. Estimated risks for first diagnoses of depression were similar or lower. The researchers caution that further studies are warranted to examine this association.
New Data on Physical Inactivity Researchers from the Centers for Disease Control and Prevention (CDC) analyzed data from the 2014 Behavioral Risk Factor Surveillance System for all 50 states and the District of Columbia to examine patterns of inactivity among adults ages 50 years and older by selected characteristics. Among the findings: • Inactivity was higher for women (29.4%) than men (25.5%). • The percentage of inactivity by race and ethnicity varied: Hispanics (32.7%), non-Hispanic Blacks (33.1%), non-Hispanic Whites (26.2%), and other groups (27.1%). • Inactivity significantly increased with age: 25.4% for people ages 50–64 years, 26.9% for people ages 65–74 years, and 35.3% for people 75 years and older. • By region, inactivity was highest in the South (30.1%), followed by the Midwest (28.4%) and the Northeast (26.6%). Inactivity was lowest in the West (23.1%). For more information visit cdc.gov/physicalactivity/index.html.
