- Perceção do estado de saúde e da qualidade de vida numa amostra de celíacos portuguesesPublication . Pimenta-Martins, Ana; Pinto, Elisabete; Gomes, Ana M. P.The treatment of celiac disease is a gluten-free diet (GFD). The compliance witha GFD is dependent on multiple factors, which include, possibly, the quality of life (QoL).Objective: To evaluate the perception of health status and QoL in a sample of Portuguese celiacpatients, relating it to the compliance of the GFD.Material and methods: Transversal study which data collection was based on a structured ques-tionnaire prepared to be self-applied and filled in online. The QoL was evaluated throughShort-Form health survey 36 (SF-36). Categorical variables were described through proporti-ons and continuous variables were described through mean and standard deviation or medianand interquartile range.Results: The study included 195 Portuguese individuals, with a median age of 32 years. About67% of respondents believed to enjoy very good or good health. The highest mean scores wereobtained for the domains ‘‘physical functioning’’ and ‘‘role-physical’’ and the lowest scoresfor the domains ‘‘vitality’’ and ‘‘general health’’. Women had significantly lower scores forthe domains ‘‘bodily pain’’, vitality’’ and ‘‘mental health’’. There was no association foundbetween the perception of QoL and compliance with the GFD. Participants with more recentdiagnosis had lower scores in all domains of the SF-36.Conclusions: The celiac respondents rated their general health status and QoL in better levelsthan the Portuguese population in general. The QoL was not associated with compliance of theGFD.

- A culture-sensitive semi-quantitative FFQ for use among the adult population in Nairobi, Kenya: development, validity and reproducibilityPublication . Vila-Real, Catarina; Pimenta-Martins, Ana; Magu, Jack-Susan; Kunyanga, Catherine; Mbugua, Samuel; Katina, Kati; Pinto, ElisabeteObjective: To develop a semi-quantitative FFQ and to evaluate its validity and reproducibility for the assessment of total dietary intake of Kenyan urban adult population, given its non-existence in Kenya. Design: The current study adopted a cross-sectional design. A culture-sensitive semi-quantitative FFQ was developed and its validity was tested relative to thre non-consecutive 24-h recalls (24hR). Reproducibility was tested by the test–retest method, with a 3-week interval. Spearman’s correlation coefficients and intra-class correlation coefficients were calculated for several macro- and micronutrients. Cross-classification into quartiles and Bland and Altman plots were analysed. Setting: Nairobi county (Dagoreti South and Starehe constituencies). Participants: A convenient sample was recruited in three different clusters in Nairobi. Results: A culture-sensitive 123-food-item semi-quantitative FFQ showed higher nutrient intakes compared with the 24hR (total energy median 12543·632 v. 8501·888 kJ, P < 0·001). Energy-adjusted and deattenuated Spearman’s correlations for macronutrients ranged between 0·21 (total fat) and 0·47 (protein). The agreement in the same quartile varied from 28 % (protein) to 41 % (carbohydrates). Including adjacent quartiles, the range increased: 76 % (protein and fat) to 81 % (carbohydrates). The extreme disagreement was low. The first FFQ application resulted in higher mean values for all nutrients compared with the second FFQ (total energy median 12459·952 v. 10485·104 kJ, P < 0·001). Energy-adjusted correlations for macronutrients ranged from 0·28 (carbohydrates) to 0·61 (protein). Intra-class correlation coefficients for macronutrients were moderate, between 0·6 and 0·7. Conclusions: The developed semi-quantitative FFQ was shown to be a valid and reproducible tool for ranking urban adult Kenyans according to their dietary intake.
- Nutritional value of indigenous whole grain cereals millet and sorghumPublication . Vila-Real, Catarina; Pimenta-Martins, Ana; Maina, Ndegwa; Gomes, Ana; Pinto, ElisabeteWorldwide population growth expectations increase the pressure to find ways to increase agro-food production in a sustainable manner, be it by increasing production capacity, cultivating currently natural areas or changing crop consumption patterns. Cereals are staple foods and the most frequently consumed are maize, wheat and rice. However, the production of these cereals may become insufficient for the growing needs. Millet and sorghum are traditional cereal crops, able to growth in adverse drought conditions, and do not need many resources to be harvested Furthermore, they reveal very interesting nutritional profiles, including macro and micronutrients and bioactive compounds. We would like to highlight their fiber content, since fiber inadequacy is a worldwide condition and its adverse effects on health are well described. Over time, these indigenous cultures have become less popular than other cereals, due to their organoleptic and technological proprieties. However, techniques like bio-fortification, fortification, genetic improvement, fermentation, malting, and germination among others can be used to improve their technological properties and enhance their nutritional profile.
