More boys than girls among undernourished Cameroon teens

01.02.2010
There are major differences in how well nourished Cameroonian teenagers are. Differences between city/countryside, boys/girls, and among individuals with high and low socioeconomic status are described by Léonie Nzefa Dapi in the dissertation she is defending at Umeå University in Sweden.

Cameroon's population are changing their eating habits. Instead of traditional diets they are consuming more and more processed, sweet, and fat foods. The rapid shift in dietary habits is taking place at the same time as people are getting less and less physically active.

This has resulted in a rather high incidence of overweight individuals, high blood pressure, cardiovascular diseases, and type-2 diabetes. Nutrition is important during the adolescence period during for growth, health, cognitive development, and school achievement.

The aim of the dissertation is to estimate boys and girls dietary intake, body measurements, and physical activity in various social groups and to study how teenagers, in cities and in the countryside, perceived food.

Girls and boys between the ages of 12 and 16 were randomly selected from schools in rural and urban areas. The percentage of overweight was three times higher among girls (14 percent) than among boys (4 percent). Stunted growth was twice as common among teenagers in the city with low socioeconomic status (12 percent) compared to those with high status (5 percent). Rural youths had more muscle mass than urban youths. In rural areas they ate to survive and maintain their health. Urban youths with low socioeconomic status also ate to maintain their health, while those of higher status ate for fun.

More than 30 percent of youth in cities skipped breakfast. Urban adolescents with high socioeconomic status, and girls, reported more often that they ate snacks and most food groups.

More than half of the youths had a protein intake below recommendations.
Twenty-six percent of young people had a fat intake below recommendations, and one fourth had a fat intake above recommendations. A Major proportion of the teenagers had an intake of micronutrients that was below the recommended level. Boys and youths with low socioeconomic status reported higher energy burning and physical activity than girls and youths with high socioeconomic status. Both under-and over-reporting of energy intake was common among the youths.

The study shows that nutritional deficiency, stunting, and obesity as well as excess weight were common among teenagers in Cameroon. It is therefore necessary to set up preventive programs targeting both over- and undernourished school children. Such a program needs to take into account gender and socioeconomic differences.

On Friday, February 5, Léonie Nzefa Dapi, Department of Public Health and Clinical Medicine, Epidemiology, and Global Health, Umeå University, will defend her dissertation titled Socioeconomic and sex differences in adolescents' dietary intake, anthropometry and physical activity in Cameroon, Africa.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
