Dietary assessment methods in epidemiologic studies.

Abstract: Diet is a major lifestyle-related risk factor of various chronic diseases. Dietary intake can be assessed by subjective report and objective observation. Subjective assessment is possible using open-ended surveys such as dietary recalls or records, or using closed-ended surveys including food frequency questionnaires. Each method has inherent strengths and limitations. Continued efforts to improve the accuracy of dietary intake assessment and enhance its feasibility in epidemiological studies have been made. This article reviews common dietary assessment methods and their feasibility in epidemiological studies.

Association of Household Food Security with Dietary Intake;Based on the Third (2005) Korea National Health and Nutrition Examination Survey (KNHANES III)

Abstract: Although food insecurity might be associated with poor dietary intake, this relationship has not been researched in Korea. This study examined the association of food security with dietary intake from the third Korea National Health and Nutrition Examination Survey. Food security was measured by a self-reported hunger measure on the dietary situation of subjects' households in the previous year and approximately 2/3 of the subjects lived in food-insecure households. Dietary intake was based on a 24-hour dietary recall. Food insecurity was significantly associated with low nutrients intake and nutrients intake compared to dietary reference intakes (DRI) was also lower among subjects in food-insecure households. Overall diet quality based on dietary diversity score (DDS) was worse in food-insecure subjects. Food security should be considered an important issue to public health because dietary change due to food insecurity may affect health status.

Elevated Serum Aminotransferase Level as a Predictor of Intracerebral Hemorrhage Korea Medical Insurance Corporation Study

Abstract: Background and Purpose— Serum aminotransferase levels are known to be associated with cardiovascular risk factors, but the relation with stroke incidence is not well known. We investigated the relation between serum aminotransferase levels and the incidence of stroke. Methods— We measured serum aspartate and alanine aminotransferase levels and traditional cardiovascular risk factors in 108 464 Korean men, aged 35 to 59 years, in 1990 and 1992. Serum aminotransferase levels were classified into 3 categories (<35, 35 to 69, and ≥70 IU/L). The outcomes were hospital admissions and deaths from stroke subtypes (ischemic stroke, intracerebral hemorrhage [ICH], and subarachnoid hemorrhage [SAH]) from 1993 to 2002. Results— During the 10 years, 1728 ischemic, 1051 hemorrhagic (718 ICH and 222 SAH), and 243 unspecified stroke events occurred. After adjustment for age and other traditional risk factors and according to Cox proportional-hazards models, serum aminotransferase level had an independent positive associa...

Cardiovascular disease and risk factors in Asia: a selected review.

Abstract: Cardiovascular disease (CVD) prevention in Asia is an important issue for world health, because half of the world’s population lives in Asia. Asian countries and regions such as Japan, the Republic of Korea, the People’s Republic of China, Hong Kong, Taiwan, and the Kingdom of Thailand have greater mortality and morbidity from stroke than from coronary heart disease (CHD), whereas the opposite is true in Western countries.1 The reasons why this specific situation is observed in countries with rapid and early-phase westernization, such as Japan and South Korea, are very interesting. The Seven Countries Study conducted by Keys et al2 in 1957 found that Japanese populations had lower fat intake, lower serum total cholesterol, and lower CHD than populations in the United States and Scandinavia, in spite of higher smoking rates. The serum total cholesterol level in Japan has increased rapidly since World War II in accordance with an increase in dietary fat intake from 10% of total energy intake per capita per day to 25%.1,2 Despite this increase, the specific characteristic of lower CHD incidence and mortality than that in Western countries has persisted.3,4 Whether Japanese people and certain other Asian populations have different risk factors for CHD than Western populations has been a subject of discussion for quite some time. In this article, we discuss the existence of higher stroke rates and lower CHD rates in Asian countries than in Western countries and the respective risk factors for this on the basis of extensive reviews of cohort studies. We also discuss whether these risk factors differ from those of Western countries. Along with this, we examine the relationship between serum total cholesterol and total stroke and its subtypes. We also address the emerging problems and important issues for CVD prevention in Asia. An extensive …

Incidence of malignancy in adult patients with rheumatoid arthritis: a meta-analysis

Abstract: Patients with rheumatoid arthritis (RA) are at an increased risk of malignancies compared with the general population. This has raised concerns regarding these patients, particularly with the widespread use of immunomodulating therapies, including biologic disease-modifying antirheumatic drugs (DMARDs). We performed a systematic literature review and analysis to quantify the incidence of malignancies in patients with RA and the general population to update previously published data. A literature search was conducted that was consistent with and similar to that in a meta-analysis published in 2008. MEDLINE, BIOSIS Previews, Embase, Derwent Drug File and SciSearch databases were searched using specified search terms. Predefined inclusion criteria identified the relevant observational studies published between 2008 and 2014 that provided estimates of relative risk of malignancy in patients with RA compared with the general population. Risk data on overall malignancy and site-specific malignancies (lymphoma, melanoma and lung, colorectal, breast, cervical and prostate cancer) were extracted. The standardized incidence ratios (SIRs; a measure of risk) relative to the general population were evaluated and compared with published rates. A total of nine publications met the inclusion criteria. Seven of these reported SIRs for overall malignancy; eight for lymphoma, melanoma, and lung, colorectal and breast cancer; seven for prostate cancer; and four for cervical cancer. Compared with those in the general population, the SIR estimates for patients with RA suggest a modest increased risk in overall malignancy, as previously observed. Patients with RA continued to show an increased risk of lymphoma and lung cancer compared with the general population. Overall, SIR estimates for colorectal and breast cancers continued to show a decrease in risk, whereas cervical cancer, prostate cancer and melanoma appeared to show no consistent trend in risk among patients with RA compared with the general population. The additional data evaluated here are consistent with previously reported data. Patients with RA are at an increased risk of lung and lymphoma malignancies compared with the general population. Quantifying differences in malignancy rates between non-biologic and biologic DMARD-treated patients with RA may further highlight which malignancies may be related to treatment rather than to the underlying disease.
