“…Few epidemiological studies, however, have evaluated the validity of dietary patterns. 6,7,[19][20][21] The aim of the present work was to evaluate relative validity of a semi-quantitative food frequency questionnaire compared to 24DRs to identify dietary patterns in an adult Mexican population. We derived three major dietary patterns in this study of the adult Mexican population, which were qualitatively similar across the two sources of dietary data.…”

“…For those reasons, it is useful to evaluate the validity of the food frequency questionnaire (FFQ) for assessing identification of dietary patterns in a particular study population. 7 While studies have evaluated the reproducibility and validity of dietary patterns in various adult populations, 6,7,[19][20][21] the validity of a semi-quantitative food frequency questionnaire (SFFQ) to derive dietary patterns in the Mexican population has not been evaluated. Therefore, we assessed the relative validity of a semiquantitative food frequency questionnaire to identify dietary patterns in an adult Mexican population.…”

Objective. To examine the validity of a semi-quantitative food frequency questionnaire (SFFQ) to identify dietary patterns in an adult Mexican population. Materials and methods. A 140-item SFFQ and two 24-hour dietary recalls (24DRs) were administered. Foods were categorized into 29 food groups used to derive dietary patterns via factor analysis. Pearson and intraclass correlations coefficients between dietary pattern scores identified from the SFFQ and 24DRs were assessed. Results. Pattern 1 was high in snacks, fast food, soft drinks, processed meats and refined grains; pattern 2 was high in fresh vegetables, fresh fruits, and dairy products; and pattern 3 was high in legumes, eggs, sweetened foods and sugars. Pearson correlation coefficients between the SFFQ and the 24DRs for these patterns were 0.66 (P<0.001), 0.41 (P<0.001) and 0. 29 (P=0.193) ResumenObjetivo. Evaluar la validez de un cuestionario de frecuencia de consumo de alimentos (CFA) para derivar patrones dietarios en población adulta mexicana. Material y métodos. Un CFA de 140-alimentos y dos recordatorios de 24-horas (24DRs) fueron obtenidos. Los alimentos fueron categorizados en 29 grupos para derivar los patrones dietarios mediante análisis factorial. La validez se evaluó mediante coeficientes de correlación intraclase y de Pearson (CCP) entre los puntajes de los patrones dietarios identificados con CFA y 24DRs. Resultados. El patrón 1 fue alto en bocadillos, carnes procesadas, comida rápida, refrescos y granos refinados; el patrón 2 estuvo caracterizado por vegetales, frutas y lácteos; y el patrón 3 se caracterizó por leguminosas, huevo, azucares, y alimentos dulces. Los CCP entre estos patrones fueron 0.66 (P<0.001), 0.41 (P<0.001) y 0.29 (P=0.193) respectivamente. Conclusión. Los datos sugieren razonable validez del CFA, utilizando análisis factorial, para derivar patrones dietarios en comparación con el 24DRs.

Dietary pattern and breast cancer risk in Japanese women: the Japan Public Health Center-based Prospective Study (JPHC Study)

Evidence that diet is associated with breast cancer risk is inconsistent. Most of the studies have focused on risks associated with specific foods and nutrients, rather than overall diet. In this study, we aimed to evaluate the association between dietary patterns and breast cancer risk in Japanese women. A total of 49 552 Japanese women were followed-up from 1995 to 1998 (5-year follow-up survey) until the end of 2012 for an average of 14·6 years. During 725 534 person-years of follow-up, 718 cases of breast cancer were identified. We identified three dietary patterns (prudent, westernised and traditional Japanese). The westernised dietary pattern was associated with a 32 % increase in breast cancer risk (hazard ratios (HR) 1·32; 95 % CI 1·03, 1·70; P trend = 0·04). In particular, subjects with extreme intake of the westernised diet (quintile (Q) Q5_5th) had an 83 % increase in risk of breast cancer in contrast to those in the lowest Q1 (HR 1·83; 95 % CI 1·25, 2·68; P trend = 0·01). In analyses stratified by menopausal status, postmenopausal subjects in the highest quintile of the westernised dietary pattern had a 29 % increased risk of breast cancer (HR 1·29; 95 % CI 0·99, 1·76; P trend = 0·04). With regard to hormone receptor status, the westernised dietary pattern was associated with an increased risk of oestrogen receptor-positive/progesterone receptor-positive tumours (HR 2·49; 95 % CI 1·40, 4·43; P trend < 0·01). The other dietary patterns were not associated with the risk of breast cancer in Japanese women. A westernised dietary pattern is associated with an increased risk of breast cancer in Japanese women.

“…Dietary recalls may be superior to FFQ and have been frequently used as a reference method in many Chinese validation studies (8)(9)(10) . To date, some foreign studies (11)(12)(13)(14)(15)(16)(17)(18) have been conducted to examine the validity of dietary patterns derived from FFQ using factor analysis. Unfortunately, no similar studies have been reported in China, with different culture-specific dietary habits.…”

In the present study, we evaluated the reproducibility and validity of dietary patterns among Chinese adult populations. A random subsample of 203 participants (aged 31-80 years) from a community-based nutrition and health survey was enrolled. An eighty-seven-item FFQ was administered twice (FFQ1 and FFQ2) 1 year apart; four 3 consecutive day, 24-h dietary recalls (24-HDR, as a reference method) were performed between the administrations of the two FFQ every 3 months. Dietary patterns from three separate dietary sources were derived using factor analysis based on twenty-eight predefined food groups. Comparisons between dietary pattern scores were made by using Pearson's or intraclass correlation coefficients (ICC), cross-classification analysis, weighted κ statistic and Bland-Altman plots; the four major dietary patterns identified from FFQ1, FFQ2 and 24-HDR were similar. Regarding reproducibility, ICC for z-scores between FFQ1 and FFQ2 were all >0·6 for dietary patterns. The 'animal and plant protein' pattern had the highest ICC of 0·870. For validity, the adjusted Pearson's correlation coefficients for dietary pattern z-scores between two FFQ and the mean of four 3 consecutive day 24-HDR ranged from 0·387 for the 'Chinese traditional' pattern to 0·838 for the 'animal and plant protein' pattern. More than 75 % of the participants were classified into the same or adjacent quartile, and <5 % were misclassified into opposite quartiles. The weighted κ ranged from 0·259 to 0·680. Bland-Altman plots indicated that no significant deviation was found between two dietary assessment methods. Our findings indicate a good reasonable reproducibility and a reasonable validity of dietary patterns derived by factor analysis in China.
