Iodine fortification of foods and condiments, other than salt, for preventing iodine deficiency disorders

Implementation strategies are meant to improve the adoption and integration of evidence-based health interventions into routine policies and practices within specific settings.  This review examined whether using these strategies improved the implementation of policies and practices in the workplace promoting:

Health risk behaviours, such as smoking and drug use, can group together during the teenage years, and engagement in these multiple risk behaviours can lead to health problems such as injury and substance abuse during childhood and adolescence, as well as non-communicable diseases later in life. The review team carried out thorough searches of multiple scientific databases and identified 70 studies that looked at ways of preventing or decreasing engagement in two or more risk behaviours, among young people aged eight to 25 years.

Eating too many calories contributes to people becoming overweight and increases the risks of heart disease, diabetes and many cancers, which are among the leading causes of poor health and premature death. Several studies have looked at whether putting nutritional labels on food and non-alcoholic drinks might have an impact on their purchasing or consumption, but their findings have been mixed.

Improving the implementation of school-based policies and practices to improve student healthThe review sought to assess how effective strategies were in supporting the implementation of school-based policies and practices to address student diet, physical activity, excessive weight gain, tobacco or alcohol use.

The review included twenty-one studies that had included a total of more than one million participants living in Africa, the Americas, and Southeast Asia. The studies covered 17 different cash transfer programs, and almost all were large cluster randomized trials. Unfortunately, though, most of the studies had a high risk of bias. This body of evidence suggests that unconditional cash transfer (UCTs) may not impact health services use among children and adults in LMICs. UCTs probably or may improve some health outcomes (i.e.

Welfare-to-work interventions and their effects on the mental and physical health of lone parents and their children Welfare-to-work interventions and their effects on the mental and physical health of lone parents and their children This review indicates that welfare to work interventions probably have little to no effect on the health of lone parents.

Later school start times for supporting the education, health, and well-being of high school studentsHigh school students are at a greater risk of sleep deprivation than other groups, both due to their changing brain chemistry and the many demands on their time, including school start times.

Health authorities and non-governmental organisations often use mass media interventions (e.g. leaflets, radio and TV advertisements, posters and social media) to encourage healthier behaviours related to physical activity, dietary patterns, tobacco use or alcohol consumption, among others. In this

New editorial on The Cochrane Library by Lawrence et al, A call to action to reshape evidence synthesis and use for nutrition policy, outlines how Cochrane can take "a proactive role in reforming evidence use in nutrition policy so as to be more relevant, transparent, and responsive to decision makers globally".
