“…Some studies have shown lower agreement between that reported and measured height than reported and measured weight, which leads to errors when classifying nutritional status (54)(55)(56) . Other studies have demonstrated a strong correlation between measured and self-reported weight (r = 0•99; P < 0•001) (57) , supporting the use of self-reported weight data in cross-sectional studies. Moreover, a study that also evaluated adolescents of both genders residing in the city of Sao Paulo (near the city of Campinas and with a similar population as that of the present study) demonstrated a high correlation between self-reported and measured weight (r > 0•94) (58) .…”

OBJECTIVE: Evaluate weight misperception among adolescents and determine associations between self-perceived weight and sociodemographic characteristics, BMI, screen time, self-rated food quantity and diet quality, weekly frequency of breakfast and the consumption of healthy and unhealthy foods. DESIGN: A cross-sectional, two-stage, probabilistic population-based study was conducted in Campinas, Brazil. Multinomial logistic regressions were run to estimate weight self-perception. SETTING: Data from the Campinas Health Survey (ISACamp) and Campinas Food Consumption Survey (ISACamp-Nutri). PARTICIPANTS: A total of 911 adolescents aged 10–19 years. RESULTS: Nearly half (47.7%) of the adolescents with overweight/obesity did not evaluate their weight properly. Weight self-perception as thin and excess weight were associated with the female gender, overweight/obesity, self-rated diet quality as poor/very poor, and eating snacks ≥3 times/week. Adolescents who did not consume breakfast daily were less likely to perceive themselves as thin. Adolescents who ate excessively were more likely and those who consumed cookies/crackers ≥3 times/week were less likely to perceive themselves as having excess weight. CONCLUSIONS: Greater weight misperception was found in overweight/obese adolescents. Gender, BMI, self-rated food quantity/diet quality, weekly frequency of breakfast and some unhealthy foods were associated with self-perceived weight. The present findings could contribute to health promotion strategies targeting adolescents.

“…Country of birth (born in Australia, other country or prefer not to say) and geographic location (Sydney, outer Sydney or regional) which was assessed by the Accessibility Remoteness Index of Australia [ 20 ]. At the conclusion of the three 24 h recalls the participants completed an online demographic questionnaire which included questions on self-reported height and weight to calculate Body Mass Index (BMI) and a sample were measured by research staff to validate this measure [ 21 ].…”

Dietary Behaviors That Place Young Adults at Risk for Future Osteoporosis

Dietary behaviors during adolescence and emerging adulthood have important consequences for peak bone mass (PBM) attainment. This study aimed to examine dietary factors that are either beneficial or detrimental to bone health and determine the major sources of calcium in the diets of a sample of young adults. A cross-sectional survey was conducted among 189 Australians aged 18–30 years. Three-day dietary intakes were collected using consecutive 24 h recall interviews. Daily totals for energy and nutrients and serves for food groups were computed. The proportion contribution of calcium (mg) from different food groups as well as calcium (mg) per portion and per 100 g were calculated. Females and males failed to meet the recommendations for dairy (91%, 82%), fruit (89%, 94%) and vegetables (74%, 86%). Eighty percent were above the recommended daily intake range for sodium. For calcium, 53% of females and 48% of males had intakes below the estimated average requirement (EAR). Milk products and dishes made the highest mean calcium contribution per portion (mg) mean standard deviation (SD), 204 mg (212) and accounted for 30% of calcium intake in females and 35% in males. As young adulthood is the final chance for dietary manipulation before PBM is achieved, these dietary risk factors should be addressed.

“…Height and weight were converted to kilograms and meters in order to calculate =BMI (kg/m 2 ). Although accuracy of self‐reported body weight remains debated, evidence suggests that this approach has reasonable validity 10 . Participants were also asked to indicate if at the time of the assessment they were currently trying to lose weight, gain weight, or if they were not currently trying to change their weight.…”

Background: Holidays are challenging for weight control and are consistently associated with weight gain. Managing holiday weight gain may be especially difficult for individuals with higher body weight or a history of overweight/obesity. The current study evaluated how individuals with a history of successful weight loss plan for the holiday season and how the use of weight control strategies was associated with weight change.Methods: A subgroup of participants in the National Weight Control Registry (NWCR) were asked to complete a survey before (November) and after the holidays (January). At pre-holiday, participants reported height, weight, and weight goals for the holiday season (lose, maintain, minimize gains, or gain), and selected the top three weight control strategies they planned to use (from a list of 18). Post-holiday, participants reported weight and how often (frequently, infrequently, or not at all) they used each of the 18 strategies throughout the holidays.Results: Individuals who completed both surveys were included in the analysis (n ¼ 683; 69% female, 93% white, 54.6 years [SD: 13.2], 26.9 kg/m 2 [SD: 5.5]). Pre-holiday, 64% of participants were currently trying to lose weight. Only 35% of the sample wanted to continue losing weight during the holiday season. The most common strategies individuals planned to use during the holiday season were evidence based (maintaining exercise, monitoring portions, tracking foods, and self-weighing). Participants gained 0.66 kg (SD: 1.85) from pre-to post-holiday and reported using an average of 12/18 strategies. A greater number of strategies were associated with less weight gain (F[1, 670] ¼ 4.28, p ¼ 0.04). Daily self-weighing (p ¼ 0.03) and prioritizing food choices (p ¼ 0.02) were individually associated with less weight gain. Discussion: Participants in the NWCR entered the holiday season with a variety of goals for their weight and used many different strategies to control their weight.Having a wider range of strategies may be helpful to navigate the challenges to weight control during the holidays.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
