To demonstrate the effectiveness of the commercial introduction of red palm oil (RPO) as a source of vitamin A (VA) for mothers and children in a non-consuming area, as a dietary diversification strategy.

A pre–post intervention design (no control area) was used to assess changes in VA intake and status over a 24-month pilot project.

The pilot project involved RPO promotion in 10 villages and an urban area in east-central Burkina Faso, targeting approximately 10?000 women and children aged < 5 years. A random sample of 210 mother–child (12–36-months-old) pairs was selected in seven out of the 11 pilot sites for the evaluation.

After 24 months, RPO was reportedly consumed by nearly 45% of mothers and children in the previous week. VA intake increased from 235 ± 23 μg retinol activity equivalents (RAE) to 655 ± 144 μg RAE in mothers (41 to 120% of safe intake level), and from 164 ± 14 μg RAE to 514 ± 77 μg RAE in children (36 to 97%). Rates of serum retinol < 0.70 μmoll−1 decreased from 61.8 ± 8.0% to 28.2 ± 11.0% in mothers, and from 84.5 ± 6.4% to 66.9 ± 11.2% in children. Those with a lower initial concentration of serum retinol showed a higher serum retinol response adjusted for VA intake.

Commercial distribution of RPO was effective in reducing VA deficiency in the pilot sites. While it is promising as part of a national strategy, additional public health and food-based measures are needed to control VA malnutrition, which remained high in the RPO project area

To study pregnant women's diet at food and nutrient levels and how these match recommendations; to describe how factors such as education level, economy and folk dietetics influence the women's food choice; and to give suggestions for the improvement of nutrition education in the existing antenatal care systems.

Thirty pregnant women in the last trimester were interviewed three times using a 24-hour dietary recall with weighing of foods and recipes of dishes. Interviews regarding health, nutrition and socio-economic status, and measurements of weight and height of the women, were conducted.

Rural parts of Salem District, Tamil Nadu, South India.

The women's diet (without supplements) was insufficient in energy and all nutrients except fat, compared with the Indian recommendations. Aggravating low intakes of micronutrients were found which were reflected in low intakes of foods other than rice. Eating customs and economy appeared to influence the women's food choice negatively in relation to recommendations while factors such as education level, family type, pregnancy number and folk dietetics did not seem to have a negative effect. The amounts of foods recommended, especially green leafy vegetables, must be shown to the women. The nutrition advice given by all levels of health providers must be the same and based on cheap, local, commonly consumed foods.

Nutrition-related disorders, including vitamin A deficiency (VAD) and chronic diseases, are serious problems in the Federated States of Micronesia (FSM). Many suggest that these disorders are new problems related to dietary and lifestyle changes. In the past four decades, imported foods, such as white rice, flour, sugar, refined foods and fatty meats, have increasingly replaced local foods in the diet.

A literature review was conducted to understand underlying issues related to dietary change and obtain insights for nutrition research and interventions.

Published and unpublished papers from different disciplines were reviewed and collated for information on food and nutrition in FSM. Topics covered were historical background, local foods, infant and child feeding, dietary assessment, and nutritional status. Particular focus was on information and data relating to VAD, the primary topic that led to the review of the literature.

FSM, a tropical country of abundant agricultural resources, has suffered a great loss in production and consumption of local foods. Inconsistent external and internal government policies and food aid programmes have contributed to the problem. Further research on the nutrient content of local foods and factors affecting production, acquisition and consumption is needed, as well as a broad, well-planned, intersectoral intervention aimed at dietary improvement for all age groups in the population.

The impact on vitamin A status of the distribution of vitamin A during national immunisation days (NIDs) has not been well established despite strong promotion by international agencies and donors. Using a pre–post design, the change in prevalence of vitamin A deficiency was examined in pre-school children in Mali.

Two cross-sectional surveys were conducted in Mopti region, the first in March 1997 before this strategy was adopted and the second in March 1999, four-and-a-half months after a mass distribution of vitamin A during NIDs.

We compared the vitamin A status of children aged 12 to 66 months targeted in 1999 by NIDs with the status of children in the same age group in 1997. Infectious events of the previous two weeks were concurrently recorded. Within the 1999 sample, the status of recipient and non-recipient children was also compared.

In 1997, the prevalence of xerophthalmia (defined by the presence of night blindness and/or Bitot spots) was 6.9% (95% confidence interval (CI) 5.1–9.2) and the modified retinol dose response (MRDR) test proved abnormal in 77.8% of 12–66-month-old children (95% CI 68.27–85.17). In 1999 this picture had improved significantly, both for xerophthalmia prevalence, 3.3% (95% CI 2.1–5.2), and abnormal MRDR test response, 63.1% (95% CI 54.25–71.23). The infectious morbidity rates between 1997 and 1999 tended to decrease. No significant improvement was found among children older than those targeted by NIDs. In 1999, children who received vitamin A had a lower risk for xerophthalmia (3.0% for recipients vs. 8.7% for non-recipients) and experienced fewer infectious events.

The clinical and biological vitamin A status of pre-school children improved between 1997 and 1999. Mass distribution of vitamin A appears to reduce the occurrence of xerophthalmia and would seem to be associated with a decrease in other related illnesses. Vitamin A supplementation during NIDs should be given a high priority when vitamin A deficiency remains a public health problem.

To study risk factors associated with overweight and obesity among adolescents enrolled in private high schools in the city of Pelotas, southern Brazil.

This was a case–control study. The subjects were 264 overweight (body mass index (BMI) ≥85th percentile of the National Center for Health Statistics (NCHS) reference population) and 264 non-overweight (BMI > 5th and <85th NCHS percentiles) adolescents identified by means of an anthropometric survey which included 1608 students. The adolescents were weighed, measured and interviewed about food habits and physical activity at school. Parents provided their own weights and heights when contacted by telephone, and parental BMI was calculated.

Hierarchical multiple conditional logistic regression showed that overweight and obesity were positively associated with mother's (odds ratio (OR) 2.86, 95% confidence interval (Cl) 1.43–5.74) and father's (OR 2.43, 95% Cl 1.37–4.30) BMI ≥ 30 kg m−2, being overweight before 10 years of age (OR 2.26, 95% Cl 1.30–3.90) and the habit of dieting (OR 3.53, 95% Cl 1.76–7.22). Having more than three meals per day was found to be a protective factor against overweight and obesity (OR 0.54, 95% Cl 0.29–1.00).

The present study showed that a family history of obesity, overweight during childhood and the habit of dieting for weight-loss purposes are factors associated with obesity during adolescence. The habit of having more than three daily meals turned out to be a protective factor against overweight. These results suggest the necessity for early intervention at the family and general community levels aimed at the prevention of obesity through actions directed towards the modification of established behaviours.
