ABSTRACT

Because eating habits are inseparably linked with people's physical health, effective behaviour interventions are highly demanded to promote healthy eating among older people. The aim of this systematic review was to identify effective diet interventions for older people and provide useful evidence and direction for further research. Three electronic bibliographic databases-PubMed, Scopus and Web of Science Core Collection were used to conduct a systematic literature search based on fixed inclusion and exclusion criteria. English language peer-reviewed journal articles published between 2011 and 2016 were selected for data extraction and quality assessment. Finally, a total of 16 studies were identified. The studies' duration ranged from three weeks to seven years. The majority of studies were carried out in European countries. Seven studies had a moderate quality while the remaining studies were at a less than moderate level. Three dietary educational interventions and all meal service related interventions reported improvements in older people's dietary variety, nutrition status, or other health-related eating behaviours. Multicomponent dietary interventions mainly contributed to the reduction of risk of chronic disease. The results supported that older people could achieve a better dietary quality if they make diet-related changes by receiving either dietary education or healthier meal service. Further high-quality studies are required to promote healthy eating among older people by taking regional diet patterns, advanced information technology, and nudging strategies into account.

ABSTRACT

OBJETIVO Avaliar a distribuição da ingestão de ácido fólico e a segurança de diferentes doses de suplementos em mulheres em idade reprodutiva. MÉTODOS Foram utilizados dados de consumo a partir de dois dias não consecutivos de registro alimentar de 6.837 mulheres em idade reprodutiva (19 a 40 anos) participantes do Inquérito Nacional de Alimentação, módulo da Pesquisa de Orçamentos Familiares 2008-2009. Médias e percentis de consumo habitual de folato natural e ácido fólico foram estimados utilizando o método do National Cancer Institute . Cinco cenários foram simulados somando-se diferentes doses diárias de fortificação (400 mcg, 500 mcg, 600 mcg, 700 mcg e 800 mcg) ao ácido fólico oriundo dos alimentos consumidos pelas mulheres. Comparou-se o total de ácido fólico (dieta + suplemento) com o nível máximo de ingestão tolerável (UL = 1.000 mcg) para definir a dose segura de suplementação. RESULTADOS Mulheres com ingestão habitual de ácido fólico acima do nível máximo de ingestão tolerável foram observadas para doses de suplemento de 800 mcg (7,0% das mulheres). Abaixo desse valor, qualquer dose de suplementação mostrou-se segura. CONCLUSÕES O uso de suplementos de até 700 mcg de ácido fólico mostrou-se seguro. .

OBJECTIVE To evaluate the distribution of folic acid intake and the safety of different doses of supplements in women of childbearing age. METHODS Data were used from two non-consecutive days of food records of 6,837 women of childbearing age (19-40 years old) participants of the National Food Survey, a module of the Household Budget Survey 2008-2009. Means and percentiles of usual consumption of natural folate and folic acid were estimated using the National Cancer Institute method. Five scenarios were simulated by adding different daily doses of fortification (400 mcg, 500 mcg, 600 mcg, 700 mcg and 800 mcg) to folic acid derived from food consumed by the women. To define a safe dose of the supplement, the total folate (dietary + supplement) was compared with the tolerable upper intake level (UL = 1,000 mcg). RESULTS Women with usual intake of folic acid above the tolerable upper intake levels were observed only for doses of supplement of 800 mcg (7.0% of women). Below this value, any dose of the supplement was safe. CONCLUSIONS The use of supplements of up to 700 mcg of folic acid was shown to be safe. .

ABSTRACT

A gravidez e a lactação aumentam as necessidades nutricionais. O objetivo deste estudo foi comparar a ingestão alimentar e a prevalência de inadequação de ingestão de nutrientes entre gestantes, lactantes, mulheres em idade reprodutiva. Dois dias de registros alimentares de 322 gestantes e 751 lactantes foram comparados com 6837 mulheres não gestantes e não lactantes entre 19 a 40 anos de idade, a partir de uma amostra representativa a nível nacional. A prevalência de inadequação de ingestão de nutrientes foi estimada pelo método National Cancer Institute usando a necessidade média estimada (EAR) como ponto de corte, exceto para o sódio em que o nível de ingestão tolerável (UL) foi utilizado. Gestantes, lactantes e mulheres em idade reprodutiva não diferiram em relação ao consumo médio de 18 grupos de alimentos, exceto o arroz, que foi mais consumido pelas lactantes. A prevalência de inadequação de nutrientes em gestantes foi maior em relação às mulheres em idade reprodutiva para a vitamina B6 (59% versus 33%). Entre as lactantes prevalência foi maior para a vitamina A (95% versus 72%), vitamina C (56% versus 37%), vitamina B6 (75% vs 33%), e zinco (64% versus 20%). A porcentagem da ingestão de sódio acima do valor máximo tolerável foi superior a 70% entre as mulheres estudadas. A ingestão inadequada é muito freqüente entre todas as mulheres e aumenta durante a gravidez e lactação.
