“…There is also risk of nonresponse bias in NHANES, with more recent data release years having reportedly fewer college graduates and higher income individuals compared with earlier cycle years, which is not sufficiently mitigated with current weighting procedures. 45 , 46 Strengths include the large nationally representative sample size, careful in‐person data collection procedures used in NHANES, and 20 years of data, establishing a trend. Another strength includes controlling for age distributions and smoking status, which is important when investigating hypertension.…”

“…Data from cycle years 2019 to 2020 were not included in this study due to the increasing challenges with nonresponse bias and the likelihood that the COVID‐19 pandemic had an impact on the partial data collection for the 2019 to 2020 cycle. 45 , 46 Data were analyzed in 2‐year increments to observe trends in the prevalence of hypertension among MA adults and WA adults. Recognized risk factors for hypertension were also compared between the groups and included age, sex, smoking status, BMI, and abdominal obesity (via WHtR).…”

Background Acculturation affects hypertension prevalence among Hispanic people, but there have been no recent analyses specifically focused on Mexican American (MA) people. We sought to determine age‐adjusted hypertension prevalence, abdominal obesity, and acculturation trends among MA adults and non‐Hispanic White adults. Methods and Results Data from the NHANES (National Health and Nutrition Examination Survey) were analyzed in 2‐year increments to observe trends in hypertension and risk factors (age, sex, body mass index, smoking status, abdominal obesity, waist‐to‐height ratio (WHtR), education, and income). Acculturation was based on three commonly used measures. The sample included 30 920 adults. Age‐adjusted hypertension prevalence is higher in MA adults (52.7%) than White adults (48.3%). Hypertension risk factors—age, obesity prevalence, WHtR, acculturation—all significantly increased among MA adults, while smoking declined. Higher acculturation scores increased hypertension likelihood (odds ratio [OR], 1.44 [95% CI, 0.91–1.97]) for MA adults compared with those with lower acculturation scores. White adults with elevated WHtR >0.5 had a 40% higher risk of hypertension than those with WHtR <0.5, but among MA adults, elevated WHtR did not increase risk for hypertension. There was a significant increase in hypertension prevalence among MA adults from 2003 to 2018 at an average biennial rate of 2.23%. There was no change in hypertension prevalence among White adults from 1999 to 2018. Conclusions Over 20 years of NHANES, more highly acculturated MA adults were at greater risk for hypertension, despite declines in smoking and controlling for age, sex, obesity status, education, and income. Finding ways to promote more traditional lifestyle and eating habits for MA adults could be a beneficial approach to reducing hypertension risk factors in this population.

“…The National Health and Nutrition Examination Survey (NHANES) was designed by the National Center for Health Statistics (NCHS) to assess the health and nutritional status of the U.S. deinstitutionalized population using a complex multi-stage cluster probability sampling design 15 . The survey protocol for data collection was authorized by the Ethical Review Board of the National Centre for Health Statistics, and all participants signed an informed consent form 16 .…”

Whether Klotho plays any role in hypothyroidism is unknown. This study aimed to determine the relationship between serum Klotho levels and hypothyroidism in older adults. From the 2007 to 2012 National Health and Nutrition Examination Survey (NHANES), 1444 older adults aged 65–79 were included in this cross-sectional study. Hypothyroidism was diagnosed using participants' reports of current medications and TSH tests. Klotho was measured using an enzyme-linked immunosorbent assay. The relationship between serum Klotho levels and hypothyroidism in older people was analyzed by one-way analysis of variance, multiple linear regression models, subgroup analyses, interaction tests, smoothed curve fitting, and threshold effects. A total of 209 (14.47%) participants were identified as having hypothyroidism. Serum Klotho (ln transformation) is independently and significantly negatively associated with the risk of hypothyroidism after complete adjustment for confounders (OR = 0.49, 95% CI 0.31–0.80; P = 0.0039). The results remained stable based on subgroup analyses and interaction tests. However, we observed an inverted U-shaped curve between the two using a smoothed curve fitting in the subgroups of 70 < age ≤ 75 years and females, with inflection points of 6.26 and 6.17, respectively. The results of our study indicate that serum Klotho levels negatively correlate with hypothyroidism among older adults.

“…The FCID provides recipes that disaggregate mixed dishes from national dietary surveys into commodity ingredients (agricultural products), which can then be linked to sustainability data from other databases ( Figure 1 ). Compared with other food and commodity composition databases, the data infrastructure of the FCID is more compatible with linkage to sustainability databases, is easier to maintain on a regular basis, and is the most commonly used for diet sustainability studies that use dietary data from the National Health and Nutrition Examination Survey (NHANES), which is the richest source of nationally representative dietary data in the United States and is the principal source of information for developing nutrition policy [ 34 , 35 ]. However, the FCID has not been officially updated since 2010 which severely limits advancements in sustainability research that are needed to answer important policy questions.…”
