To examine the association between overweight and obesity and serum ferritin among women of reproductive age (15–49 years) in Nicaragua, considering the effect of α1-acid glycoprotein (AGP), a marker of inflammation.

We analysed data from the 2004–05 Nicaraguan Integrated Surveillance System for Nutrition Interventions. Three logistic regression models were analysed with low serum ferritin (<15 μg/l) as the dependent variable: (i) overweight or obese status and covariates; (ii) model 1 plus AGP; and (iii) model 1 restricted to only women with normal AGP levels (≤1·0 g/l).

Included in this analysis were 832 non-pregnant mother/caregivers (15–49 years) surveyed in 2004–2005.

In the sample, prevalence of overweight and obesity was 31·8 % and 19·2 %, respectively, and 27·6 % had low serum ferritin. In model 1, the adjusted OR of low serum ferritin was 0·74 (95 % CI 0·52, 1·05) for overweight women and 0·42 (95 % CI 0·26, 0·65) for obese women. In model 2, AGP was significantly independently associated with low serum ferritin (adjusted OR=0·56, 95 % CI 0·34, 0·92) while the adjusted OR for overweight and obesity were largely unchanged. Excluding women with elevated AGP did not appreciably affect the relationship between overweight or obesity and low serum ferritin (model 3).

Overall, in this population of reproductive-age women, obese women were less likely to have low serum ferritin levels, and this was independent of inflammation as measured by AGP.

The Nutritional Support for Africans Starting Antiretroviral Therapy (NUSTART) trial was designed to determine whether nutritional support for malnourished HIV-infected adults starting antiretroviral therapy (ART) can improve early survival. Appetite is related to health outcomes in this population, but the optimal appetite metric for field use is uncertain. We evaluated two measures of appetite with the goal of improving understanding and treatment of malnutrition in HIV-infected adults.

Malnourished (BMI<18·5 kg/m2) HIV-infected adults starting ART.

Appetite measurements, by short questionnaire and by weight of maize porridge consumed in a standardized test, were compared across time and correlated with changes in weight. Appetite questionnaire scores, from polychoric correlation, and porridge test results were normally distributed for Tanzanians (n 187) but clustered and unreliable for Zambians (n 297). Among Tanzanian patients, the appetite score increased rapidly from referral for ART, plateaued at the start of ART and then increased slowly during the 12-week follow-up. Change in appetite questionnaire score, but not porridge test, correlated with weight change in the corresponding two-week intervals (P=0·002) or over the whole study (P=0·05) but a point estimate of hunger did not predict weight change (P=0·4).

In Tanzania change in appetite score correlated with weight change, but single point measurements did not. Appetite increases several weeks after the start of ART, which may be an appropriate time for nutritional interventions for malnourished HIV-infected adults.

To assess key experts’ opinion regarding essential competencies required for effective public health nutrition practice within the health-care system of Iran.

Qualitative study using the modified Delphi technique through an email-delivered questionnaire.

Iran.

Fifty-five experts were contacted through email. The inclusion criterion for the study panel was being in a relevant senior-level position in nutrition science or public health nutrition in Iran.

In the first round, forty-two out of fifty-five experts responded to the questionnaire (response rate=76 %). A sixty-five-item questionnaire was designed with nine competency areas, including ‘nutrition science’, ‘planning and implementing nutritional interventions’, ‘health and nutrition services’, ‘advocacy and communication’, ‘assessment and analysis’, ‘evaluation’, ‘cultural, social and political aspects’, ‘using technology’ and ‘leadership and management’. All experts who had participated in the first round completed a modified version of the questionnaire with seventy-seven items in the second round. The experts scored ‘nutrition science’ as the most essential competency area, while more applied areas such as ‘management and leadership’ were less emphasized. In both rounds, the mean difference between the opinions of the necessity of each area was 5·6 %.

The Iranian experts had general agreement on most of the core competency areas of public health nutritionists. The results indicated the need for capacity building and revisions to educational curricula for public health nutritionist programmes, with more emphasis on skill-based competency development.
