Determinants of anaemia among pregnant women in rural Uganda.

INTRODUCTION: In spite of intervention efforts, in Uganda, as in other developing countries, high levels of anaemia among pregnant women continue. Anaemia among women of reproductive age (15-49 years) is a matter of national concern. This study was carried out to assess determinants of anaemia in Kiboga district. METHODS: This was a single cross-sectional, descriptive survey. The anaemia status of the pregnant women was determined by measuring their haemoglobin levels. Possible determinant factors including socio-economic characteristics, knowledge, attitudes, practices and food intake were assessed using a structured questionnaire. RESULTS: Results showed that the prevalence of anaemia among pregnant women in Kiboga district was high enough (63.1%) to be described as a severe public health problem. The uptake and utilisation of the public-health intervention package to combat anaemia in pregnancy was low, with iron/folic acid supplementation at 13.2%, use of intermittent preventive treatment of malaria 45.4%, and use of de-worming medicines 14.5%. Women from households without a functional radio were 2.07 times more likely be anaemic (95%CI, 1.08-3.00) compared with women from households where there was a functional radio. There was little awareness and functional knowledge about anaemia among pregnant women. CONCLUSION: The high prevalence of anaemia observed in Kiboga district can be attributed to poverty and limited access to nutrition and health education information which lead to low uptake and utilization of the public-health intervention package to combat anaemia in pregnancy.

Effect of preparation conditions on protein secondary structure and biofilm formation of kafirin.

Various extraction and drying conditions for the isolation of kafirin from dry-milled, whole grain sorghum have been investigated, with a view to optimizing extraction of the protein for commercial food coatings and packaging films. The addition of sodium hydroxide to an aqueous ethanol extractant increased the yield and solubility of kafirin. Subsequent heat drying at 40 degrees C was shown to cause the kafirin to aggregate as indicated by an increase in intermolecular beta-sheets. Extraction of the flour using ethanol (70%, w/w) with 0.5% (w/w) sodium metabisulfite and 0.35% (w/w) sodium hydroxide at 70 degrees C followed by freeze-drying of the protein was found to produce a yield of 54% kafirin with good film-forming properties. The kafirin films were assessed for their sensory properties, tensile strength, strain, and water vapor permeability. Fourier transform infrared spectroscopy was used to study the secondary structure of the extracted kafirins. The best films were made with kafirin containing a large proportion of nativelike alpha-helical structures with little intermolecular beta-sheet content as indicated by the Fourier transform infrared reflectance peak intensity ratios associated with these secondary structures. The principal factor affecting the secondary structure of the protein appeared to be the temperature at which the protein was dried. Heat drying resulted in a greater proportion of intermolecular beta-sheets. Any industrial-scale extraction must therefore minimize protein aggregation and maximize native alpha-helical structures to achieve optimal film quality.

Impact of a tetanus toxoid immunization mass campaign on neonatal tetanus mortality in Aceh Province, Indonesia.

Neonatal tetanus mortality declined dramatically in Pidie district (Aceh Province) Indonesia between 1984 and 1987. Baseline and follow-up survey results demonstrated an 85% reduction in neonatal tetanus mortality during this period, from 32.1/1000 live births to 4.9/1000 live births. During 1985 a tetanus toxoid mass campaign was conducted in Pidie district which resulted in 84% of women 10-45 years of age receiving two tetanus toxoid injections. Analysis of the results of the two surveys provides very strong evidence of the impact of the tetanus toxoid mass campaign on neonatal tetanus mortality.
