  • Ages 22 to 79 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: The study population comprised 4,243 non-Hispanic Blacks, including 3,837 U.S.-born (90.4%) and 406 foreign-born (9.6%). Compared to U.S.-born Blacks, a higher proportion of foreign-born Blacks were male, had attained a higher level of education, were classified as normal or overweight, had never been a smoker, engaged in physical activity, and had lower energy intake. In comparison to those who were in the U.S. for <10 years, more foreign-born Blacks who were in the U.S. for ≥30 years were current smokers (14.8% vs. 5.0%, respectively), had higher income (IPR of ≥4.00: 43.5% vs 7.9%, respectively), and a higher percent with a college degree or higher (39.4% vs. 18.3%, respectively). Foreign-born Blacks residing in the U.S. for ≥30 years reported higher BMI in comparison to those residing in the U.S. for <10 years (28.8 vs. 26.7 kg/m2).

About this study

Official title: Diet Quality Among U.S.-Born and Foreign-born Non-Hispanic Blacks: NHANES 2003-2012 Data

This study compares the diet quality between U.S.-born and foreign-born non-Hispanic Blacks using pooled NHANES data.

Read the detailed description

This study uses the Alternative Healthy Eating Index-2010 (AHEI-2010) and Dietary Approach to Stop Hypertension (DASH) scores to compare diet quality between U.S.-born (n=3,837) and foreign-born (n=406) non-Hispanic Black adults aged 22-79y, based on pooled nationally representative data (NHANES 2003-2012); as well as by length of U.S. residency. Association between nativity and diet quality was done using multivariable-adjusted linear regression for the continuous total diet quality scores and their components, or multinomial (polytomous) logistic regression for categorical tertiles (low, medium, or high) of the total scores and their components. The study found that foreign-born Blacks had significantly higher AHEI-2010 and DASH scores compared to U.S-born Blacks, and more favorable intakes for many of the score components. Among foreign-born Blacks, diet quality did not significantly differ by length of residency. Foreign-born Blacks were more likely to be in the high than low tertile for fruit (including and excluding fruit juice), vegetables (excluding starchy vegetables), percent whole grains, and omega-3 fatty acids. Overall, the study suggests that foreign-born Blacks have better diet quality compared to their U.S.-born counterparts. Considering nativity among U.S. Blacks in nutrition research and public health efforts may therefore improve accuracy of characterizing dietary intakes and facilitate development of targeted nutrition interventions to reduce diet-related diseases in the diverse Black population in the U.S.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adapted AHEI-2010

    Components include: fruit (excluding fruit juice) (s/d); vegetables (excluding white potatoes) (s/d); whole grains (oz-equivalents/d); sugar-sweetened beverages (s/d); nuts, legumes, and vegetable protein (oz-equivalents/d); red/processed meat (s/d); long-chain omega-3 fats (EPA+DHA; mg/d); polyunsaturated fats (PUFA; % kcal/d); sodium (mg/d); and alcohol (drinks/d). Potential range of 0-100 points and higher scores indicative of higher diet quality

    Measured: 2003-2012

Secondary outcomes (1)

  1. Adapted DASH score

    Quintile-, food-based dietary score assessing adherence to the DASH diet, which was developed as a dietary approach to prevent and treat hypertension. Components of the revised score include vegetables, fruit, whole grains, nuts and legumes, sodium, red and processed meat, and sugar-sweetened beverages.

    Measured: 2003-2012

Questions about this trial

What is this clinical trial studying?

An observational study of Diet Habit, run by Sara C. Folta.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adapted AHEI-2010 (time frame: 2003-2012). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03266497.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Aug 2017.
