American Journal of Public Health November issue research highlights:

Shift workers have a higher risk of poor mental health

Shift workers are at higher risk for poor mental health, particularly symptoms of depression, a new systemic review in the November issue of APHA’s American Journal of Public Health finds. People who do shift work, defined as working outside the standard hours of 7 a.m. to 6 p.m., often have their sleep-wake cycle disrupted, with implications for their physical and mental.

In the new meta-analysis, researchers reviewed seven longitudinal studies involving more than 28,000 people. They found that compared to people who work standard hours, shift workers had a 30% higher risk of poor mental health and depression. Women were especially affected, with a 70% higher risk of depression among shift workers, compared to women who worked day shifts.

Noting that poor mental health costs the U.S. health care system millions and affects quality of life, the study researchers called for programs that can minimize poor mental health among shift workers.

Court interventions can boost student fitness

When courts force school districts to meet physical education requirements, student health can improve, according to a study in the November AJPH.

While California education laws require that elementary students receive 200 minutes a day of physical education, not all schools were in compliance as of 2010. Lawsuits were filed against 128 school districts, leading to settlements that forced schools to meet the requirement.

Researchers looked at physical activity data for fifth-graders attending state schools before and after the court settlements, finding that the litigation led to a 1-percentage point increase in the proportion of fifth-graders meeting cardio-respiratory fitness standards.

Schools that were not in compliance with the physical education requirements before the lawsuits had a higher percentage of Hispanic, black and low-income students and were less likely to meet physical fitness standards.

While the litigation was beneficial, researchers suggested that it would be more cost-effective for the Department of Education to mandate tracking of physical education time and reporting.

Program linked to decreases in firearm violence, but increases in other violence

An innovative Richmond, California, program to prevent gun violence led to a drop in firearm-related hospital visits and crimes in the city, according to a study in the November AJPH. Operation Peacemaker Fellowship, implemented by the Richmond Office of Neighborhood Safety, was an 18-month program involving community residents who were believed to be most associated with firearm crimes. The fellowship included individual cognitive behavioral therapy, case management, substance abuse treatment, social service navigation and a $1,000 a month stipend.

The program was associated with a significant reduction in firearm-related violence, with 55% fewer deaths per hospital visits and 43% fewer crimes, the new AJPH study found.

However, the study also found that the program was associated with increases in nonfirearm-related violence, with 16% more deaths per hospital visits and 3% more crimes. Researchers suggested the increases may be because other weapons or bodily force were substituted when firearms were lessened, or that removing key people from participation in violence created a power void, among other possibilities.

As the Operation Peacemaker Fellowship has received nationwide attention and is being replicated in other cities, study researchers advised that organizers measure nonfirearm-related violence during their work.

Preterm birth rates in China vary by region

Across China, 7.3% of all annual births are preterm, though rates are higher in less developed areas of the country, a study in the November issue of AJPH finds.

Complications from preterm birth — defined as delivery that occurs before 37 weeks of gestation — were the leading cause of death for children under 5 in China as of 2015. Preterm births accounted for 7.3 per 100 total births and 6.7 per 100 of live births from 2015 to 2016, the study found.

Researchers found that preterm birth rates varied widely by region. An 11.4% rate was recorded for southwest China and 10.3% for northwest China. The regions are less developed than other parts of the country, the researchers noted, supporting a link between low socio-economic status and preterm births.

Factors associated with preterm births included sexually transmitted disease, history of miscarriage or stillbirth and fetal abnormalities.
