“…Given that dietary habits could change over time, food consumption assessment at a single time point possibly results in nondifferential bias. Nevertheless, in nutritional epidemiology, it is always assumed that an adult's dietary habits would not change dramatically during a short period [25]; also, it has been indicated that the methods using baseline diet data only generally result in a weaker association than do these using the cumulative averages [49]. Second, all individuals included in our study were American adults aged 55e74 years; moreover, 90.9% of them were non-Hispanic white; 36.6% were college students; and 51.0% were current or former smokers.…”

Background & aims: Type 2 diabetes prevention diet confers a lower risk of type 2 diabetes, which exhibits overlapping mechanisms with pancreatic cancer. We performed a prospective study to examine whether adherence to this dietary pattern is associated with a reduced risk of pancreatic cancer. Methods: A population-based cohort of 101,729 American adults was identified. A dietary diabetes risk reduction score was computed to reflect adherence to this dietary pattern, with higher scores representing greater adherence. Cox regression was used to compute hazard ratios (HRs) for pancreatic cancer incidence. Prespecified subgroup analyses were used to identify the potential effect modifiers. Results: After an average follow-up of 8.86 years (900,871.67 person-years), a total of 402 pancreatic cancer cases were observed. In the fully adjusted model, participants in the highest quartile of dietary diabetes risk reduction score were found to have a reduced risk of pancreatic cancer compared with those in the lowest quartile [HR quartiles 4 versus 1 : 0.62; 95% confidence interval (CI): 0.44, 0.86; P trend ¼ 0.004], which remained in a series of sensitivity analyses. Subgroup analyses further found that this favorable association was more pronounced in current or former smokers (HR quartiles 4 versus 1 : 0.48; 95% CI: 0.30, 0.77) than in never smokers (HR quartiles 4 versus 1 : 0.71; 95% CI: 0.44, 1.15), although the interaction test did not reach statistical significance (P interaction ¼ 0.095). Conclusions: Greater adherence to type 2 diabetes prevention diet is associated with a lower risk of pancreatic cancer in this US population. More studies are needed to confirm our findings.

“…DDS is more accessible and simpler for middle-aged and older people since only have to consider the frequency of food intake [10,11]. As the widely-used tool to evaluate diet quality, it has been validated among different populations and confirmed to be associated with several age-related diseases, such as diabetes [12,13], anxiety [14], disability [15], and all-cause mortality [16,17]. To our knowledge, there have been limited studies conducted thus far to investigate the relationship between DDS and MCI.…”

Background: The evidence concerning dietary diversity and cognitive function remains insufficient. Objective: To investigate the association of dietary diversity score (DDS) with mild cognitive impairment (MCI) and cognitive performance in different domains. Methods: Data from The Lifestyle and Healthy Aging of Chinese Square Dancer Study was used in this study. DDS was constructed based on the intake frequencies of 9 food groups assessed by a validated food frequency questionnaire. MCI was diagnosed by Petersen’s criteria. A neuropsychological test battery was used to assess the performance on cognitive domains, and test scores were standardized to Z scores. Multiple linear regression models and logistic regression models were used to estimate the β and odds ratios and their 95% CIs, respectively. Results: Among 1,982 participants, the mean (SD) age was 63.37 (5.00) years, 1,778 (89.71%) were women, and 279 (14.08%) had MCI. Compared to the DDS quartile (0, 6], the multivariable-adjusted odds ratios (95% CI) were 0.74 (0.48, 1.15) for DDS quartile (6, 7], 0.65 (0.43, 0.97) for DDS quartile (7, 8], and 0.55 (0.37, 0.84) for DDS quartile (8, 9]. Furthermore, higher DDS was positively associated with better performance of cognitive domains, including global cognitive function (β= 0.20, 95% CI: 0.12, 0.30), episodic memory (β= 0.21, 95% CI: 0.07, 0.35), attention (β= 0.15, 95% CI: 0.03, 0.26), language fluency (β= 0.24, 95% CI: 0.10, 0.38), and executive function (β= – 0.24, 95% CI: – 0.38, – 0.10). Conclusions: This study indicated that higher DDS was associated with better cognitive function among middle-aged and older Chinese people.

“…However, the dietary habits of individuals do not change dramatically and studies using a single measurement of dietary information often yield weaker association indicators. 44 This study, despite using one‐time measure, provides a strong association, suggesting that low‐fat dairy products have a definitive preventive impact against lung cancer and are even more significant than the results presented in this study.…”

Low‐fat dairy consumption and the risk of lung cancer: A large prospective cohort study

BackgroundDespite the possible contribution of dairy products to the development or prevention of cancers, there is a lack of epidemiological evidence linking low‐fat dairy consumption to the risk of developing lung cancer. This research was conducted to fill this knowledge gap.MethodsThe data for this research were collected from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial. The Cox proportional risk model was employed to evaluate the link between low‐fat dairy consumption and the risk of developing lung cancer. Hazard ratios (HRs) and 95% confidence intervals (CIs) were measured in both unadjusted and adjusted models. A series of predefined subgroup analyses were performed to identify potential effect modifiers, and several sensitivity analyses were conducted to assess the stability of the findings.ResultsThe study included data from 98,459 individuals. During a total of 869,807.9 follow‐up person‐years, 1642 cases of lung cancer were observed, with an incidence of 0.189 cases for every 100 person‐years. In the fully adjusted model, participants in the highest quartile of low‐fat dairy consumption had a significantly decreased risk of lung cancer compared to the ones in the lowest quartile (HRquartile 4 vs. 1: 0.769, 95% CI: 0.664, 0.891, ptrend = 0.005). The restricted cubic spline plot revealed an inverse nonlinear dose–response relationship between low‐fat dairy consumption and lung cancer risk (pnonlinearity = 0.008). Subgroup analyses demonstrated that the inverse association was stronger among participants with higher daily caloric intake (pinteraction = 0.031). Various sensitivity analyses produced consistent results.ConclusionConsuming more low‐fat dairy products is significantly linked to a reduced risk of developing lung cancer, indicating that an appropriate increase in the use of low‐fat dairy products may help prevent lung cancer.
