BACKGROUND Food frequency questionnaires (FFQ) are used for epidemiological studies. Because of the wide variations in dietary habits within different populations, a FFQ must be developed to suit the specific group. To date, no FFQ has been developed for Japanese children. In this study, we developed a FFQ to assess the regular dietary intake of Japanese children. The FFQ included questions reg...

BACKGROUND Validation studies of dietary instruments developed for epidemiological studies have typically used some form of diet record as the standard for comparison. Recent work suggests that comparison with diet record may overestimate the ability of the epidemiological instrument to measure habitual dietary intake, due to lack of independence of the measurement errors. The degree of regress...

The study objective was to validate a food frequency questionnaire (FFQ) to assess calcium, vitamin D and vitamin K intakes in overweight and obese postmenopausal community-dwelling women. The FFQ was validated against intakes derived from a 5-day diet record (5DDR) that also included assessment of supplement intake. Strong correlations between methods were observed for all nutrients (r = 0.63,...

BACKGROUND The etiology of the geriatric syndrome frailty is multifactorial. Besides hormonal and inflammatory processes, nutritional influences may be of major relevance. In this cross-sectional study, the association between dietary quality and frailty was investigated. METHODS In 192 community-dwelling older volunteers (>75 years), an interview-based food frequency questionnaire was used t...

Shopping at low-cost supermarkets has been associated with higher obesity rates. This study examined whether attitudes toward healthy eating are independently associated with diet quality among shoppers at low-cost, medium-cost, and high-cost supermarkets. Data on socioeconomic status (SES), attitudes toward healthy eating, and supermarket choice were collected using a telephone survey of a rep...

OBJECTIVE To evaluate the relative validity of an FFQ for assessing nutrient intakes in 12-month-old infants. DESIGN AND SETTING The FFQ was developed to assess the diets of infants born to women in the Southampton Women's Survey (SWS), a population-based survey of young women and their offspring. The energy and nutrient intakes obtained from an interviewer-administered FFQ were compared with...

BACKGROUND & AIMS The incidence of osteoporotic fractures is lower in countries in the Mediterranean basin. Virgin olive oil, a key component of the Mediterranean Diet (MDiet), with recognised beneficial effects on metabolism and cardiovascular health, may decrease the risk of osteoporotic fractures. The aim to this study was to explore the effect of chronic consumption of total olive oil and i...

background: chronic obstructive pulmonary disease (copd) is a major public health problem worldwide. smoking is the number one cause of copd; however, genetic, environmental and dietary factors contribute to the etiology of this disease. in this study, we assessed the association between three diet quality indices -the healthy eating index-2005 (hei-2005), the healthy eating index-2010 (hei-201...

The aims of this work were as follows: 1) to determine whether a purified diet currently used for studies with rats was acceptable for reproductive studies in frogs; and 2) to determine whether frogs are sensitive to a deficit of boron (B) in the diet. Adult Xenopus laevis were fed a nonpurified beef liver and lung (BLL) diet (310 microg B/kg), a purified diet supplemented with boron (+B; 1850 ...
