Positive impact of mass media campaign on bed net use in Cameroon

A mass media health education intervention in support of investments in malaria control commodities such as insecticide-treated mosquito bed nets can result in significant, large-scale positive health changes, according to a study conducted in Cameroon.

The study found that Cameroonians with at least one bed net in their household were more likely to use the bed nets after being exposed to the “KO Palu” (Knock Out Malaria) national campaign. Approximately 298,000 adults and more than 221,000 of their children under age five slept under a bed net because of the knowledge, motivation, and/or timely reminder provided by KO Palu NightWatch activities.

The health communication program cost less than $0.16 per adult reached, and less than $1.62 per additional person protected by a net.

According to the World Health Organization’s World Malaria Report 2011, every one of Cameroon’s 19.6 million citizens is at risk of malaria, with 71 percent of them living in high transmission areas. More than 1.8 million suspected cases of malaria were recorded countrywide in 2010, along with over 4,500 recorded malaria-attributed deaths. Malaria was estimated to be responsible for 19 percent of under-five child deaths in 2008, more than any other single cause.

mHealth in the developing world: Is it effective?

The use of mobile communication technology has been shown to improve access to health services and medical information, but two systematic reviews published in PLoS Medicine indicate a lack of evidence that mHealth is an effective solution to health challenges in the developing world.

The majority of studies on mHealth effectiveness are conducted in industrialized countries and may not apply to low- and middle-income countries. According to the systematic reviews, three out of 75 trials that aimed to assess whether mobile technology interventions could improve health behavior or disease management were from developing countries.

Previous studies in sub-Saharan Africa have found mobile phone text messaging to improve adherence to HIV treatment, while others have shown their failure to do so. The new reviews found that for disease management, the only two mHealth applications with sufficient evidence of benefit are ones related to adherence to antiretroviral therapy and smoking cessation.

The reviews call for additional rigorous mHealth tests in low- and middle-income settings.

Slowdown in fight against malaria

An effective concerted effort to strengthen malaria control globally in the last decade has had the greatest impact in countries with high malaria transmission. Close to 60 percent of the 1.1 million lives saved during this period were in the 10 highest burden countries. However, the expansion of funding for malaria prevention and control has leveled off in recent years, and progress in the delivery of some life-saving commodities has slowed. These developments are signs of a slowdown that could threaten to reverse the recent gains in the fight against one of the world’s leading infectious diseases, according to the World Malaria Report 2012.

The number of long-lasting insecticidal neets delivered to endemic countries in sub-Saharan Africa dropped from a peak of 145 million in 2010 to an estimated 66 million in 2012. The expansion of indoor residual spraying programs also leveled off, with coverage levels in the World Health Organization (WHO) African Region staying at 11 percent of the population at risk (77 million people) between 2010-2011.

The malaria burden is concentrated in 14 endemic countries, which account for an estimated 80 percent of malaria deaths. The Democratic Republic of the Congo and Nigeria are the most affected countries in sub-Saharan Africa, while India is the most affected country in South-East Asia.

The report indicates that international funding for malaria appears to have reached a plateau well below the level required to reach the health-related Millennium Development Goals and other internationally-agreed global malaria targets.

While the plateauing of funding is affecting the scale-up of some interventions, the report documents a major increase in the sales of rapid diagnostics tests, from 88 million in 2010 to 155 million in 2011, as well as a substantial improvement in the quality of tests over recent years. Deliveries to countries of artemisinin-based combination therapies (ACTs), the treatment recommended by the WHO for the treatment of falciparum malaria, also increased substantially, from 181 million in 2010 to 278 million in 2011, largely as a result of increased sales of subsidized ACTs in the private sector.

The report summarizes information received from 99 countries with on-going transmission and other sources, and updates the analyses presented in the 2011 report. Malaria is an entirely preventable and treatable vector-borne disease. In 2010, an estimated 219 million cases occurred globally, while the disease killed about 660,000 people, mostly children under age five years.

Motivating HIV testing among MSM using internet and mobile phones

Men who have sex with men (MSM) have the highest HIV prevalence in Peru, yet they are underserved by traditional preventive programs. In Peru, the Internet and mobile phones have emerged as an effective and convenient tool to reach this population. A study published in PLoS ONE identifies five key themes that should be considered when designing an effective campaign to motivate HIV testing.

1. Overcome fear of getting tested for HIV. Previous studies identify “fear of the consequences of a positive test result” as the main barrier for not getting tested among MSM. Since the 1980s, HIV testing campaigns in Peru have focused on fear, stigmatizing the disease and causing people to avoid getting tested out of fear of being positive. Future campaigns need to counteract this by providing motivational messages that transmit calmness and explain that HIV is now a chronic and treatable disease.
2. Increase risk perception. MSM with high-risk practices often do not perceive themselves at risk. A brief explanation on the modes of transmission along with messages that can prompt participants to remember common risk situations they may have experienced would be useful to better understand the risks.
3. Explain logistics. A successful campaign should include the marketing of the personnel, the place, information about the process, including the test itself, and the price of testing. The personnel include the professionals who will perform the HIV test and who will provide the results. The place includes the physical location where the test will be conducted, the operating hours, general attractiveness, comfort and accessibility. The price refers not only to monetary cost but also intangible costs such as embarrassment and psychological strain.
4. Avoid stigmatizing and stereotyping content. Avoid language that implies gay men are promiscuous or more likely to have HIV. Use neutral characters (not stereotyped caricatures of gay men), as well as neutral language (absence of gay-related jargon) because either they were considered stigmatizing for gay-identified MSM, or because they will not feel identified within the heterosexually-identified MSM.
5. Use appropriate layout and language. Study participants recommended that all text based information, when possible, should always be presented with images. Language should be simple and colloquial but not vulgar. The Layout should avoid the use of red, dark or gloomy colors. When possible, use humor because it makes information easier to understand and to remember.

These results serve as the basis to design an effective campaign to motivate HIV testing among gay and non-gay identified MSM in Lima, Peru, the study concludes.

Plain cigarette packs may reduce smoking appeal

Plain packaging and removal of descriptors on cigarette packs may reduce the appeal of smoking for teens and young adults, and consequently reduce the likelihood of smoking, according to a study of young women aged 16-26 years in Brazil.

Study participants were asked to rate three types of cigarette packages (standard branded, plain packaging, and plain packaging with no descriptors, e.g., flavors). Branded cigarette packs were rated as significantly more appealing, better tasting and smoother than plain packs and were associated with greater style and sophistication.

Removing descriptors from the plain packs further decreased the ratings of appeal, taste and smoothness, and also reduced associations with positive attributes.

Leisure time exercise lengthens life expectancy, study finds

Adults who participate in leisure time physical activity, even below recommended levels, are likely to reduce their risk of death, according to a review study that included 650,000 people over age 40 years.

Life expectancy could be increased by as much as 4.5 years, regardless of weight. Even obese people who were very active were found to live an average of 3.1 more years than inactive people of normal weight.

The results may help convince currently inactive people that a modest physical activity program may have health benefits, even if it does not result in weight loss, the study concludes.
