Under-reporting of food intake is frequent among Brazilian free-living older persons: a doubly labelled water study

The WE-RISE™ multi-domain intervention: a feasibility study for the potential reversal of cognitive frailty in Malaysian older persons of lower socioeconomic status

BACKGROUND

Cognitive frailty (CF) is an emerging concern among older persons, particularly within lower socioeconomic statuses (SES) populations. Currently, there is limited evidence on the potential reversibility of CF through multi-domain interventions within this demographic. This study aimed to investigate the effectiveness of the WE-RISE™ multi-domain intervention in addressing the potential reversibility of CF among community-dwelling older persons of lower SES, the intervention effects on multiple health dimensions, and to determine if WE-RISE™ is of low cost.

METHODS

This 24-week randomised controlled trial included 55 community-dwelling older persons of lower SES with CF, who were randomised into either the WE-RISE™ intervention group (n = 27), or the control group receiving usual care (n = 28). The WE-RISE™ intervention comprised of 12 weeks of instructor led, community-based intervention, followed by 12 weeks of WE-RISE™@Home. CF status, cognitive and physical function, nutrition, disability, health-related quality of life, exercise self-efficacy and depression were assessed at baseline, 12th and 24th weeks. Changes in CF status was analysed descriptively, while intervention effects were analyzed with split plot ANOVA. The cost of the WE-RISE™ intervention was calculated using activity-based costing.

RESULTS

At baseline, all participants in both the intervention and control groups (100%) were classified as CF. Following 12 weeks of the WE-RISE™ intervention, 74.1% of participants in the experimental group no longer met the criteria for cognitive frailty, with 63% maintaining this improvement at 24 weeks. In contrast, the CF status of participants in the control group remained largely unchanged, with only 10.7% showing improvement at 12 weeks and falling to 3.6% at 24 weeks. Significant intervention effects were observed for cognition, physical function, body composition, disability, health-related quality of life and self-perceived exercise self-efficacy (p < 0.05) following participation in WE-RISE™. The cost per intervention session was RM4.06 (≈ RM3.88), and the cost per subject for 48 sessions was RM194.74 (≈ RM187.01).

CONCLUSION

The WE-RISE™ multi-domain intervention has demonstrated potential in reversing CF among older persons of lower SES, leading to significant improvements across multiple health dimensions at a low cost. WE-RISE™ shows promise to enrich the well-being of ageing societies, contribute to societal health, and ensure equitable access to healthcare, supporting broader implementation by enhancing equitable access to health programs and addressing the needs of older persons, WE-RISE™.

Comparison of total daily energy expenditure with dietary reference intakes values in a sample of urban, relatively active Brazilian adults: A doubly labeled water study

OBJECTIVE

This report aimed to describe the results of total daily energy expenditure (TDEE) assessed by doubly labeled water (DLWTDEE) and the adequacy of the dietary reference intakes (DRI) equations to estimate energy requirements (DRIER).

METHODS

A cross-sectional and observational study in a convenience sample of 40 healthy Brazilian adults (≥20 years; 21 women) living in a tropical urban region. Basal metabolic rate (BMR) was measured by indirect calorimetry, DLWTDEE was compared with DRIER using individual calculated physical activity level (PAL = DLWTDEE/BMR) in its estimation.

RESULTS

BMR (5043 ± 548 kJ/day in women and 6213 ± 656 kJ/day in men), DLWTDEE (8372 ± 1324 kJ/day and 11 453 ± 1834 kJ/day), and PAL (1.66 ± 0.17 and 1.85 ± 0.30, respectively) were significantly higher in men. The DRIER significantly overestimated DLWTDEE by 13.7 ± 8.3% and 12.7 ± 10.7% in women and men, respectively.

CONCLUSION

In the present sample of relatively active urban Brazilian subjects, the DRIER yielded inaccurate estimation of DLWTDEE. More data from low- and moderate-income countries are necessary to develop accurate estimates of TDEE.

Misreporting of dietary energy intake obtained by 24 h recalls in older adults: a comparison of five previous methods using doubly labeled water

BACKGROUND/OBJECTIVE

To test five different methods to detect misreporting in comparison to doubly labeled water in a sample of older adults.

SUBJECTS/METHODS

A cross-sectional study with thirty-eight Brazilian community-dwelling older adults aged 60-84 years, who had their total energy expenditure measured by doubly labeled water (TEE_DLW). Dietary data were collected by two 24 h recalls. Misreporting was compared with estimates obtained by the methods proposed by: Goldberg et al. [1, 2], Black [3], McCrory et al. [4], Huang et al [5], and Rennie et al [6]. Bland-Altman plots with 95% limits of agreement were constructed to assess the agreement between rEI and TEE_DLW. Weighted kappa coefficients, sensitivity and specificity analyses, and area under the receiving operator characteristic curve (AUC) were used to test the performance of each method.

RESULTS

The prevalence of under-reporters (UR) and over-reporters (OR) obtained by the reference (DLW) were 57.9% (n = 22) and 5.3% (n = 2), respectively. Black [3] presented the worst agreement and McCrory et al. [4] the best one to accurately classify individuals in the three categories of energy reporting. McCrory et al. [4] had the best performance in the sensitivity and specificity analyses detecting UR and plausible reporters.

CONCLUSIONS

There was a high prevalence of misreporting, especially underreporting, in this sample of community-dwelling Brazilian older adults. The study showed a wide variation in the accuracy of predictive methods to handle misreporting, with none of the equations showing outstanding agreement with the reference. When DLW is not available, a valid method should be chosen to address energy intake reporting.

Dietary Risk Factors for Cardiovascular Disease among Low-Income Haitian Adults: Findings from a Population-Based Cohort

Poor diets are responsible for a large burden of noncommunicable disease (NCD). The prevalence of modifiable dietary risk factors is rising in lower-income countries such as Haiti, along with increasing urbanization and shifts to diets high in sugar, salt, and fat. We describe self-reported dietary patterns (intake of fruits, vegetables, fried food, sugar-sweetened beverages, and added salt and oil) among a population-based cohort of low-income adults in Port-au-Prince and assess for associated sociodemographic factors (age, sex, income, education, body mass index). Among 2989 participants, the median age was 40 years, and 58.0% were women. Less than 1% met the World Health Organization recommendation of at least five servings/day of fruits and vegetables. Participants consumed fried food on average 1.6 days/week and sugar-sweetened beverages on average 4.7 days/week; young males of low socioeconomic status were the most likely to consume these dietary risk factors. The vast majority of participants reported usually or often consuming salt (87.1%) and oil (86.5%) added to their meals eaten at home. Our findings underscore the need for public health campaigns, particularly those targeting young males and household cooks preparing family meals at home, to improve dietary patterns in Haiti in order to address the growing NCD burden.

Investigating sex differences in the accuracy of dietary assessment methods to measure energy intake in adults: a systematic review and meta-analysis

BACKGROUND

To inform the interpretation of dietary data in the context of sex differences in diet-disease relations, it is important to understand whether there are any sex differences in accuracy of dietary reporting.

OBJECTIVE

To quantify sex differences in self-reported total energy intake (TEI) compared with a reference measure of total energy expenditure (TEE).

METHODS

Six electronic databases were systematically searched for published original research articles between 1980 and April 2020. Studies were included if they were conducted in adult populations with measures for both females and males of self-reported TEI and TEE from doubly labeled water (DLW). Studies were screened and quality assessed independently by 2 authors. Random-effects meta-analyses were conducted to pool the mean differences between TEI and TEE for, and between, females and males, by method of dietary assessment.

RESULTS

From 1313 identified studies, 31 met the inclusion criteria. The studies collectively included information on 4518 individuals (54% females). Dietary assessment methods included 24-h recalls (n = 12, 2 with supplemental photos of food items consumed), estimated food records (EFRs; n = 11), FFQs (n = 10), weighed food records (WFRs, n = 5), and diet histories (n = 2). Meta-analyses identified underestimation of TEI by females and males, ranging from -1318 kJ/d (95% CI: -1967, -669) for FFQ to -2650 kJ/d (95% CI: -3492, -1807) for 24-h recalls for females, and from -1764 kJ/d (95% CI: -2285, -1242) for FFQ to -3438 kJ/d (95% CI: -5382, -1494) for WFR for males. There was no difference in the level of underestimation by sex, except when using EFR, for which males underestimated energy intake more than females (by 590 kJ/d, 95% CI: 35, 1,146).

CONCLUSION

Substantial underestimation of TEI across a range of dietary assessment methods was identified, similar by sex. These underestimations should be considered when assessing TEI and interpreting diet-disease relations.

Validity of Dietary Assessment Methods When Compared to the Method of Doubly Labeled Water: A Systematic Review in Adults

Accuracy in quantifying energy intake (EI) using common dietary assessment methods is crucial for interpreting the relationship between diet and chronic disease. The aim of this systematic review was to evaluate the validity of dietary assessment methods used to estimate the EI of adults in comparison to total energy expenditure (TEE) measured by doubly labeled water (DLW). Articles in English across nine electronic databases, published between 1973 and February 2019 were retrieved. Studies were included if participants were adults (≥18 years) and used the DLW technique to measure TEE compared to self-reported EI. A total of 59 studies were included, with a total of 6,298 free living adults and a mean of 107 participants per study. The majority of studies including 16 studies that included a technology based method reported significant (P < 0.05) under-reporting of EI when compared to TEE, with few over-reporting EI. Misreporting was more frequent among females compared to males within recall based dietary assessment methods. The degree of under-reporting was highly variable within studies using the same method, with 24 h recalls having less variation and degree of under-reporting compared to other methods.

Phytoestrogen Concentrations in Human Urine as Biomarkers for Dietary Phytoestrogen Intake in Mexican Women

There has been substantial interest in phytoestrogens, because of their potential effect in reducing cancer and heart disease risk. Measuring concentrations of phytoestrogens in urine is an alternative method for conducting epidemiological studies. Our objective was to evaluate the urinary excretion of phytoestrogens as biomarkers for dietary phytoestrogen intake in Mexican women. Participants were 100 healthy women from 25 to 80 years of age. A food frequency questionnaire (FFQ) and a 24 h recall were used to estimate habitual and recent intakes of isoflavones, lignans, flavonols, coumestrol, resveratrol, naringenin, and luteolin. Urinary concentrations were measured by liquid chromatography (HPLC) coupled to mass spectrometry (MS) using the electrospray ionization interface (ESI) and diode array detector (DAD) (HPLC-DAD-ESI-MS). Spearman correlation coefficients were used to evaluate associations between dietary intake and urine concentrations. The habitual consumption (FFQ) of total phytoestrogens was 37.56 mg/day. In urine, the higher compounds were naringenin (60.1 µg/L) and enterolactone (41.7 µg/L). Recent intakes (24 h recall) of isoflavones (r = 0.460, p < 0.001), lignans (r = 0.550, p < 0.0001), flavonoids (r = 0.240, p < 0.05), and total phytoestrogens (r = 0.410, p < 0.001) were correlated to their urinary levels. Total phytoestrogen intakes estimated by the FFQ showed higher correlations to urinary levels (r = 0.730, p < 0.0001). Urinary phytoestrogens may be useful as biomarkers of phytoestrogen intake, and as a tool for evaluating the relationship of intake and disease risk in Mexican women.

Misreport of energy intake assessed with food records and 24-h recalls compared with total energy expenditure estimated with DLW

BACKGROUND/OBJECTIVES

The accuracy of dietary assessment methods has rarely been validated using precise techniques. The objective of this work was to evaluate the validity of energy intake (EI) estimated with food records (FRs) and 24-h recalls (24hRs) against total energy expenditure (EE) estimated by the doubly labeled water (DLW) method. In addition, the magnitude of EI under-reporting was assessed along with its associated characteristics.

SUBJECTS/METHODS

The studied group included 83 adults between 20 and 60 years of age who were recruited from a population-based sample. Within-person variation-adjusted means of EI estimated from two FRs and three 24hRs were compared with EE estimated using the DLW method multiple-point protocol. The Wilcoxon signed-rank test was used to assess the differences between EI and EE, whereas Bland-Altman and survival-agreement plots assessed the agreement between the estimates.

RESULTS

The mean EE (2540 kcal) was greater than the mean reported EI for both dietary assessment methods (FR: 1774 kcal; 24hR: 1658 kcal, P<0.01). The frequency of under-reporting was lower (20%) for EI estimated with the 24hR than that estimated with the FR (32%). Men presented lower magnitude of under-reported EI than women did. For women, differences between EI and EE were lower with FR than with 24hR. Overall, FR and 24hR showed similar performance. The mean under-reported EI was ~30% for both methods.

CONCLUSIONS

Irregular meal habits, smoking and low education were associated with the under-report of EI. Both FR and 24hR are subjected to bias suggesting the need of refining the procedures applied in dietary assessment methods.

Association between Adult Stature and Energy Expenditure in Low-Income Women from Northeastern Brazil

Background

Perinatal undernutrition may lead to important metabolic adaptations in adult life, short stature being the most visible. The present study aimed to evaluate the association between stature and total energy expenditure of low-income women.

Method

Women aged 19–45 years from low-income communities in Maceió-AL were recruited. A sample of 67 volunteers was selected and divided into either short stature (≤152.4 cm; n = 34) or non-short stature (≥158.7 cm; n = 33) group. Data on socioeconomic status, anthropometric variables, and hormonal profiles was collected. Total energy expenditure and body composition were assessed by the doubly labeled water technique with multiple points over 14 days. In addition, physical activity levels were measured with triaxial accelerometers and dietary intake data were collected using three 24-hour food records.

Results

The mean subject age was 30.94 years. Women of short stature had lower body weight and lean body mass compared to non-short women, but there were no differences in thyroid hormone concentrations or daily energy intake between the two groups. Short-stature women showed lower total energy expenditure (P = 0.01) and a significantly higher physical activity level (P = 0.01) compared to non-short women. However, the difference in total energy expenditure was no longer significant after statistical adjustment for age, lean body mass, and triiodothyronine concentrations.

Conclusion

Women with short stature present the same energy intake, but lower total energy expenditure than non-short women, even with a higher physical activity level, which suggests that they are more prone to weight gain.

Assessment of energy intake in women with chronic obstructive pulmonary disease: a doubly labeled water method study

OBJECTIVES

To maintain energy balance, reliable methods for assessing energy intake and expenditure should be used in patients with chronic obstructive pulmonary disease (COPD). The purpose of this study was to validate the diet history and 7-day food diary methods of assessing energy intake (EI) using total energy expenditure (TEE) with the doubly labeled water (DLW) method (TEEDLW) as the criterion method in outpatient women with COPD.

METHODS

EI was assessed by diet history (EIDH) and a 7-day food diary (EIFD) in 19 women with COPD, using TEEDLW as the criterion method. The three methods were compared using intra-class correlation coefficients (ICC) and Bland-Altman analyses. The participants were classified according to their reporting status (EI/TEE) as valid-reporters 0.79-1.21, under-reporters < 0.79 or over-reporters > 1.21.

RESULTS

Diet history underestimated reported EI by 28%, and 7-day food diary underestimated EI by approximately 20% compared with TEEDLW. The ICC analysis showed weak agreement between TEEDLW and EIDH (ICC=-0.01; 95%CI-0.10 to 0.17) and between TEEDLW and EIFD (ICC=0.11; 95%CI -0.16 to 0.44). The Bland-Altman plots revealed a slight systematic bias for both methods. For diet history, six women (32%) were identified as valid-reporters, and for the 7-day food diary, twelve women (63%) were identified as valid-reporters. The accuracy of reported EI was only related to BMI.

CONCLUSION

The diet history and 7-day food diary methods underestimated energy intake in women with COPD compared with the DLW method. Individuals with higher BMIs are prone to underreporting. Seven-day food diaries should be used with caution in assessing EI in women with COPD.

[Underreporting of energy intake and associated factors in a population-based study]

This study aimed to identify the prevalence of underreporting of energy intake and associated factors in a sample of 331 individuals from the population-based Health Survey in the City of São Paulo, Brazil. Energy intake was assessed by averaging two 24-hour recalls collected on nonconsecutive days. Total energy expenditure was calculated by the predictive equation, and under-reporters were defined as individuals with energy intake less than 2 standard deviations from the energy intake/predicted total energy expenditure ratio. Poisson regression was used to identify factors associated with underreporting. Prevalence of underreporting of energy intake was 15.1%, whereas individuals with overweight and dissatisfied with body weight were more likely to underreport when compared to individuals without excess weight and who were satisfied with body weight, respectively. We conclude that these factors should be considered when developing techniques to improve the accuracy of dietary assessment.

Brazilian pregnant and lactating women do not change their food intake to meet nutritional goals

BACKGROUND

Nutritional requirements are increased during pregnancy and lactation. The aim of this study was to compare the food intake and prevalence of inadequate nutrient intake among pregnant, lactating and reproductive-age women.

METHODS

Two-day dietary records of 322 pregnant and 751 lactating women were compared to those of 6837 non-pregnant and non-lactating women aged 19 to 40 years from a nationwide representative sample. The usual nutrient intake was estimated using the National Cancer Institute method, and compared to nutritional goals to estimate prevalence of inadequate intake.

RESULTS

Pregnant, lactating and reproductive-age women did not differ in their average consumption of 18 food groups, except for rice, with greatest intake among lactating women. The prevalence of nutrient inadequacy in pregnant women was higher than in reproductive-age women for folate (78% versus 40%) and vitamin B6 (59% versus 33%). In lactating women, prevalence was higher than in reproductive-age women for vitamin A (95% versus 72%), vitamin C (56% versus 37%), vitamin B6 (75% vs. 33%), folate (72% versus 40%) and zinc (64% versus 20%). The percentage of sodium intake above the upper limit was greater than 70% in the three groups.

CONCLUSIONS

Inadequate intake is frequent in women and increases during pregnancy and lactation, because women do not change their food intake. Guidelines should stimulate healthy food intake for women across the lifespan.

Alimentos mais consumidos no Brasil: Inquérito Nacional de Alimentação 2008-2009

OBJETIVO: Caracterizar o consumo alimentar mais frequente da população brasileira. MÉTODOS: Foram analisados dados referentes ao primeiro dia de registro alimentar de 34.003 indivíduos com dez anos ou mais de idade que responderam ao Inquérito Nacional de Alimentação, composto por amostra probabilística da Pesquisa de Orçamentos Familiares 2008-2009. O padrão de consumo foi analisado segundo sexo, grupo etário, região e faixa de renda familiar per capita. RESULTADOS: Os alimentos mais frequentemente referidos pela população brasileira foram arroz (84,0%), café (79,0%), feijão (72,8%), pão de sal (63,0%) e carne bovina (48,7%), destacando-se também o consumo de sucos e refrescos (39,8%), refrigerantes (23,0%) e menor presença de frutas (16,0%) e hortaliças (16,0%). Essa configuração apresenta pouca variação quando se consideram os estratos de sexo e faixa etária; contudo, observa-se que os adolescentes foram o único grupo etário que deixou de citar qualquer hortaliça e que incluiu doces, bebida láctea e biscoitos doces entre os itens mais consumidos. Alimentos marcadamente de consumo regional incluem a farinha de mandioca no Norte e Nordeste e o chá na região Sul. Houve discrepâncias no consumo alimentar entre os estratos de menor e maior renda: indivíduos no quarto de renda mais elevada referiram sanduíches, tomate e alface e aqueles no primeiro quarto de renda citaram os peixes e preparações à base de peixe e farinha de mandioca entre os alimentos mais referidos. CONCLUSÕES: Existe um padrão básico do consumo alimentar no Brasil que inclui entre os alimentos mais consumidos arroz, café, feijão, pão de sal e carne bovina, associado ao consumo regional de alguns poucos itens. Particularmente entre os adolescentes, alimentos ricos em gordura e açúcar são também de consumo frequente.

Free-living energy expenditure reduced after deep brain stimulation surgery for Parkinson's disease

BACKGROUND

The clinical picture in Parkinson's disease (PD) is characterized by bradykinesia, rigidity, resting tremor and postural instability. In advanced stages of the disease, many patients will experience reduced efficacy of medication with fluctuations in symptoms and dyskinesias. Surgical treatment with deep brain stimulation in the subthalamic nucleus (STN-DBS) is now considered the gold standard in fluctuating PD. Many patients experience a gain of weight following the surgery. The aim of this study was to identify possible mechanisms, which may contribute to body weight gain in patients with PD following bilateral STN-DBS surgery.

METHODS

Ten patients with PD were studied before bilateral STN-DBS surgery, and seven patients were studied again 3 and 12 months postoperatively. Clinical examination and resting metabolic rate with and without medical treatment was measured before and after STN-DBS. Furthermore, free-living energy expenditure, body composition, energy intake, peak oxygen consumption, maximal workload and leisure time physical activity were measured before and 3 and 12 months after surgery.

RESULTS

The STN-DBS operated patients had a significant weight gain of 4·7 ± 1·6 kg (mean ± SE) 12 months postoperatively, and the weight gain was in the fat mass. The free-living energy expenditure decreased postoperatively 13 ± 4% even though the reported dietary intake was reduced. A decreased energy expenditure took place in the non-resting energy expenditure. The reported daily leisure time activity, peak oxygen consumption and maximal workload were unchanged.

CONCLUSION

The STN-DBS operated patients have a significant postoperative weight gain, as a result of a decrease in free-living energy expenditure concomitant with an insufficient decrease in energy intake.
