Total energy intake of the US population: the third National Health and Nutrition Examination Survey, 1988-1991

Abstract

The third National Health and Nutrition Examination Survey (NHANES III) was conducted to assess the health and nutritional status of the US population. As part of the nutritional status assessment, reliable 24-h dietary recalls were collected for 14,801 examined persons. Mean (+/- SEM) energy intakes are reported for persons aged > or = 2 mo by age, sex, and race-ethnicity. Males had higher mean energy intakes than did females. Energy intakes peaked during late adolescence and young adulthood and declined thereafter. Energy intake patterns were similar among non-Hispanic whites, non-Hispanic blacks, and Mexican Americans. Underreporting was addressed by computing a ratio of energy intake (EI) to estimated basal metabolic rate (BMRest). This ratio (EI:BMRest) was 1.47 for adult males and 1.26 for nonpregnant adult females. Overweight adults had a lower mean EI:BMRest (1.09 in females and 1.28 in males). Underreporting in food consumption surveys remains problematic among females and overweight persons.

Sex ratio of total energy intake in adults: an analysis of dietary surveys

“…The inverse relation of age to the sex ratio of TEI was further enhanced by the ®nding that the sex ratio of TEI was higher in the younger age class ( 60a64 y) than in the older age class ( b 60a64 y) (P`0.0001). Men and women in the same country share a similar pattern of dietary intake throughout life, but TEI is higher in men than in women in each age class 13 (Kesteloot, 1989). TEI peaked at 16 ± 29 y for both sexes.…”

“…It is in this age range that the sex difference in TEI reaches its maximum, and then declines with advancing age. 13 Dietary assessment methods have a signi®cant impact on the sex ratio of TEI. It is evident from Table 5 …”

“…The surveys that cannot be assigned to either the 60a64 y group or the b 60a64 year group were de®ned as unable to split' group. Of the 81 surveys examined, 13 surveys 33,16,24,25,8,9,64,56,41,63,10,13,34 could be split into two sub-surveys by the above-de®ned cutoff point of age. Each of these two sub-surveys was then treated as a single survey in parts of the analysis.…”

“…Each of these two sub-surveys was then treated as a single survey in parts of the analysis. Secondly, of the 81 surveys obtained, 9 surveys 33,24,25,8,64,56,41,10,13 presented the data of TEI in ®ve or more age classes. This enabled us to perform a univariate analysis between the mean age of an age class and its corresponding sex ratio of TEI.…”

Food consumed does not account for the higher prevalence of obesity among stunted adults in a very-low-income population in the Northeast of Brazil (Maceió, Alagoas)

“…The result obtained was multiplied by an 'activity factor' of 1.4, compatible, according to the FAO/WHO/UN (1985), with a light activity pattern, which was expected in a sedentary population (Briefel et al, 1995).…”
