Analysing customer loyalty card data is a novel method for assessing nutritional quality and changes in a population's food consumption. However, prior to its use, the thousands of grocery products available in stores must be reclassified from the retailer's original hierarchical structure into a structure that is suitable for the use of nutrition and health research. We created LoCard Food Classification (LCFC) and examined how it reflects the nutritional quality of the grocery product groups. Nutritional quality was considered the main criterion guiding the reclassification of the 3574 grocery product groups. Information on the main ingredient of the product group, purpose of use and carbon footprint was also used at the more granular levels of LCFC. The main challenge in the reclassification was a lack of detailed information on the type of products included in each group, and some of the groups included products that have opposite health effects. The final LCFC has four hierarchical levels, and it is openly available online. After reclassification, the product groups were linked with the Finnish food composition database, and the nutrient profile was assessed by calculating the Nutrient-Rich Food Index (NRFI) for each product group. sd in NRFI decreased from 0·21 of the least granular level to 0·08 of the most granular level of LCFC indicating that the most granular level of LCFC has more homogeneous nutritional quality. Studies that apply LCFC to examine loyalty card data with health and environmental outcomes are needed to further demonstrate its validity. [ABSTRACT FROM AUTHOR]

Little evidence exists regarding the relationship between dietary patterns and telomere length, especially derived applying longitudinal design. The aim was to study if overall dietary pattern is associated with leukocyte telomere length (LTL) or faster telomere attrition or both. Methods The setting was longitudinal and observational. Participants were 456 men and 590 women whose birth settled in between 1934 and 1944 and who participated in the Helsinki Birth Cohort Study. Baltic sea diet score (BSDS), modified Mediterranean diet score (mMED), and dietary inflammatory index (DII.sup.®) were calculated based on a 128-item food frequency questionnaire (FFQ) collected in 2001-2004. LTL was measured twice, in 2001-2004 and in 2011-2013 by quantitative real-time polymerase chain reaction. Association between the dietary patterns and LTL were analysed by general linear models with appropriate contrasts. Results BSDS, mMED, and DII did not associate with LTL in the cross-sectional analysis in men or women. Higher mMED at baseline (2001-2004) was associated with slightly faster LTL shortening during the follow-up (standardized ß -0.08, 95% CI -0.15, -0.01). No association between mMED and LTL change was found in men. Adherence to BSDS and DII did not associate with LTL change in men or women. Conclusion Baltic sea diet, Mediterranean diet, and diet's inflammatory potential seem to have only little impact on telomere length and telomere attrition in elderly Finnish men and women.

Aims: Fruit and vegetable consumption is essential in disease prevention. Socioeconomic differences in consumption have been observed but evidence from longitudinal studies incorporating multiple socioeconomic indicators is lacking. We examined long-term fruit and vegetable consumption trajectories and multiple socioeconomic circumstances as their determinants. Methods: We used survey data from the Helsinki Health Study (phase 1 in 2000–2002, N =8960, response rate 67%; phases 2–4 in 2007, 2012 and 2017) among initially 40- to 60-year-old employees of City of Helsinki, Finland. Fruit and vegetable consumption was measured by a food frequency questionnaire and consumption times per month were calculated. Childhood (parental education, economic difficulties), conventional (own education, occupational class, household income) and material (housing tenure, wealth, current economic difficulties) socioeconomic circumstances were included. We used group-based trajectory modelling for identifying fruit and vegetable consumption trajectories and multinomial logistic regression for examining associations between socioeconomic circumstances and the trajectories. Results: Four fruit and vegetable consumption trajectories were identified: increasing higher (12%), decreasing higher (10%), stable moderate (43%) and stable low (35% of participants). Childhood, conventional and material socioeconomic circumstances were all associated with the trajectories: belonging to a lower socioeconomic group was associated with belonging to the stable low and moderate trajectories. In multivariate models, the strongest associations were found for occupational class and household wealth. Conclusions: Disadvantageous childhood and adulthood socioeconomic circumstances were associated with lower long-term fruit and vegetable consumption. Socioeconomic circumstances should be considered in attempts to promote fruit and vegetable consumption, and people with disadvantageous circumstances need to be targeted in future interventions.

Added sugar intake has been associated with several health issues, but few studies have examined its association with overall diet quality. We aimed at examining the association between added sugar intake and overall diet quality in Finnish adults. Associations between added sugar intake and sociodemographic factors, lifestyle factors, and BMI were also explored. Our data comprised 5094 adults residing in Finland who participated in the National FinHealth 2017 Study. Dietary intake was assessed by a validated FFQ. Food consumption and nutrient intakes were calculated using the Finnish national food composition database. Added sugar intake was estimated based on food categorisation and identifying naturally occurring sugar sources. Overall diet quality was assessed by the modified Baltic Sea Diet Score. The average added sugar intake was 7·6 E % in women and 8·3 E % in men in this study population. Added sugar intake was inversely associated with education (P = 0·03 women; P = 0·001 men), physical activity (P < 0·0001), and BMI in men (P = 0·003), and directly with smoking (P = 0·002 women; P < 0·0001 men). Added sugar intake was inversely associated with overall diet quality in both sexes (P < 0·0001). No interactions were found except for men's physical activity subgroups, the inverse association being stronger among active men than moderately active or inactive men (Pfor interaction = 0·005). Our findings suggest that high added sugar intake is associated with several unhealthy dietary and lifestyle habits, including poor-quality diets, smoking and leisure-time inactivity in Finnish adults. Efforts to improve diet quality should consider added sugar intake equally in the whole population. [ABSTRACT FROM AUTHOR]

Objective: To study whether diets based on the Nordic food culture and dietary recommendations are related to periodontal disease development. Methods: The data were based on the Health 2000 and 2011 Surveys (BRIF8901). The participants were aged 30‐49 in 2000, periodontally healthy, without diabetes or rheumatoid arthritis. Analyses were made in the total study population (n = 240) and among nonsmokers (n = 193) in 2011. Periodontal condition was determined in a clinical examination, and the number of teeth with deepened (≥4 mm) periodontal pockets in 2011 was used as an outcome. The diet was measured using a validated food frequency questionnaire and the quality of the diet using the Baltic Sea Diet Score (BSDS) and the Recommended Finnish Diet Score (RFDS) in 2000. Incidence rate ratios (IRRs) and 95% confidence intervals (CIs) were estimated using Poisson regression models. Results: Low scores (indicating poor diet) in both the BSDS and the RFDS were associated with the development of deepened periodontal pockets. Among nonsmokers, the associations between low dietary scores and the number of teeth with deepened periodontal pockets were stronger than among the whole study population. Conclusions: Among middle‐aged adults, poor‐quality diet appears to be associated with the development of periodontal disease. [ABSTRACT FROM AUTHOR]
