Introdução O consumo alimentar está associado com prevenção ou com risco de doenças e por isso sua estimativa pode ser utilizada como importante fonte de informação para o planejamento de políticas públicas em nutrição. Objetivo Estudar a ingestão habitual de nutrientes em uma amostra representativa de adultos e idosos residentes no município de São Paulo, segundo características sociodemográficas. Métodos Estudo transversal, com amostra representativa da população de adultos e idosos do município de São Paulo, conduzido no ano de 2003 (ISA-2003). Foi coletado um recordatório alimentar de 24 horas (R24h) para cada participante (n=1663), além de dados socioeconômicos e antropométricos. A medida de variabilidade da ingestão foi calculada por meio de duas replicações do R24h em uma subamostra desta população, no ano de 2007 (ISA-2007). A ingestão habitual foi estimada por meio do método desenvolvido pelo Iowa State University no programa PC-SIDE. As prevalências de inadequação foram calculadas pelo método da EAR como ponto de corte, segundo sexo, escolaridade do chefe da família, escolaridade do indivíduo e estado nutricional, posteriormente comparados utilizando o teste de proporções. Foram calculadas as razões de variância intrapessoal sobre a interpessoal entre os sexos. Resultados As prevalências de inadequação mais elevadas foram relativas às vitamina A (67por cento e 58por cento ), vitamina C (52por cento e 62por cento ), tiamina (41por cento e 50por cento ) e riboflavina (29por cento e 19por cento ), para o sexo masculino e feminino, respectivamente. A proporção de indivíduos com ingestão superior ao recomendado de cálcio foi menor que 2por cento e de sódio maior do que 99por cento . A prevalência de inadequação de vitaminas A, C, tiamina, riboflavina e niacina e dos minerais cobre, fósforo e selênio foi mais elevada entre os indivíduos com menor escolaridade, tanto do chefe da família como do indivíduo. Observaram-se diferenças nas frações das variâncias intrapessoais de alguns nutrientes segundo gênero. Conclusão Os adultos e idosos residentes do município de São Paulo apresentaram altas prevalências de inadequação na ingestão das vitaminas A, C, tiamina e riboflavina em ambos os sexos, principalmente entre os com menor escolaridade / Introduction Food intake is associated with prevention or risk of disease and so this estimation can be used as important source of information for planning public policy in nutrition. Objective To study the usual intake of nutrients in a representative sample of adults and older people living in São Paulo, according to sociodemographic characteristics. Methods Cross-sectional study with a representative sample of the adults and older people population in São Paulo, conducted in the year 2003 (ISA-2003). We collected a 24-hour dietary recall (24HR) for each participant (n=1663), and anthropometric and socioeconomic data. The measurement of intake variability was calculated by two replications of 24HR in a subsample of this population in 2007 (ISA-2007). The usual intake was estimated using the PC-SIDE program, which uses the method developed by Iowa State University. The prevalence of inadequacy were calculated by EAR cut-point method, according to sex, education of household head, education and nutritional status of individual, compared using proportion test. Ratios of within- to between-person variation were calculated according to sex. Results The highest prevalence of inadequate intake were related to vitamin A (67per cent and 58per cent ), vitamin C (52per cent and 62per cent ), thiamin (41per cent and 50per cent ) and riboflavin (29per cent and 19per cent ), for male and female, respectively. The proportion of individuals with more than the recommended intake of calcium was less than 2per cent and this percent of sodium was greater than 99per cent . The prevalence of inadequate intake of vitamins A, C, thiamin, riboflavin and niacin and of minerals copper, phosphorus and selenium were higher among individuals with less education, both of the head of the family as the individual. Differences were observed in the ratios of intraindividual variances of some nutrients by sex. Conclusion Adults and older people living in São Paulo presented high prevalence of inadequate intake of vitamins A, C, thiamin and riboflavin for both sexes, especially among the less educated people

<p>Food insecurity, or limited access to enough foods for an active, healthy life, characterizes the situation of 65% of US food pantry clients. Food insecurity is associated with poor dietary intake of key food groups and nutrients, diet-related chronic disease, poor physical and mental health, and reduced quality of life. Although food pantry clients are prevalently food insecure, there is a sizeable proportion of clients who are classified as food secure (FS), or report having adequate access to healthy foods. Previous studies suggest that food secure pantry clients may use pantry resources differently, and have diets that differ in quality and intake, compared to food insecure clients (including low food secure [LFS] and very low food secure [VLFS] clients). </p><p>Food pantries may be an important venue for interventions to improve food security and dietary outcomes. Since dietary intake and use of food pantries may differ by food security status, the efficacy of such interventions may also differ by food security status. A social ecological modeled (SEM), community-based intervention in the food pantry setting is promising in sustaining local change efforts and may facilitate long-term implementation of strategies to improve diet-related outcomes among food pantry clients. Therefore, the aims of this dissertation were to 1) characterize differences in diet quality and intake between FS, LFS and VLFS pantry clients; 2) explore associations between the nutritional quality of the pantry food environment (foods in stock and foods distributed to clients) and client diet quality by food security status; and 3) evaluate the intermediate effects of a SEM, community-based intervention to improve diet-related outcomes among pantry clients with comparison by food security status.</p><p>Aim 1 was addressed by examining associations between food security and both diet quality and usual intake (in separate mixed multiple linear regression models) in a cross-sectional analysis of adult food pantry clients at baseline. FS status was associated with a higher Healthy Eating Index-2010 (HEI-2010) whole grains score, as well as a higher mean usual intakes of whole grains and iron, compared to LFS status. FS status was also associated with higher mean usual intakes of dark green vegetables and total dairy compared to LFS and VLFS status.</p><p>Aim 2 was addressed by evaluating the relationship between the quality of the mix of foods in stock (pantry inventories) and distributed (client food bags) at food pantries with client diet quality, and investigating how these relationships varied by food security status, in a cross-sectional analysis of adult food pantry clients at baseline. Client food bag HEI-2010 scores were positively associated with client diet scores for the total vegetables, total fruit, total protein foods, and sodium components, while pantry inventory HEI-2010 scores were negatively associated with client diet scores for the total score and for the total fruit and fatty acids components. VLFS clients consumed more whole grains from client food bags compared to FS clients, and consumed more greens and beans from pantry inventories compared to LFS clients.</p><p>Aim 3 was addressed by evaluating longitudinal changes in adult food security, diet quality and usual intake over the first two years (baseline to midpoint) of a three-year SEM, community-based food pantry intervention‒ Voices for Food (Clinical Trial Registry: NCT0356609). Adult food security score improved in the intervention group, while HEI-2010 total score and several component scores improved in the comparison group. When comparing the change in main outcomes over time between the intervention and comparison groups, no favorable differences were observed at this intermediate time point.</p><p> </p><p>Food pantries do not comprise a homogeneous population of clients. Pantry clients have different quality diets and rely on pantries to acquire different types of foods depending on their food security status. Food pantries may be an important venue to target interventions that improve diet-related outcomes, with consideration for the complex interplay between food security status, the pantry food environment and availability of resources to prepare healthy foods. Evaluation of the final study time point, as well as further investigation of the dose-dependent effect of each intervention component and other individual community characteristics, may elucidate the relationship between the intervention and client outcomes.</p><p></p>
