“…The present study’s findings (summarized in Table 4) would be applicable for use in young South African adults aged <30 years. Height loss begins from the age of 30 years ( 42 ) and consequently these findings may not be relevant to those aged >30 years.…”

“…The current study did not include different age categories, which would have accounted for potential age-related height loss ( 42 ) . There was a lack of local South African-based anthropometric studies which have investigated the use of arm-associated height estimation methods for the calculation of true height in young South African adults.…”

ObjectiveTo investigate the accuracy of arm-associated height estimation methods in the calculation of true height compared with stretch stature in a sample of young South African adults.DesignA cross-sectional descriptive design was employed.SettingPietermaritzburg, Westville and Durban, KwaZulu-Natal, South Africa, 2015.SubjectsConvenience sample (N 900) aged 18–24 years, which included an equal number of participants from both genders (150 per gender) stratified across race (Caucasian, Black African and Indian).ResultsContinuous variables that were investigated included: (i) stretch stature; (ii) total armspan; (iii) half-armspan; (iv) half-armspan ×2; (v) demi-span; (vi) demi-span gender-specific equation; (vii) WHO equation; and (viii) WHO-adjusted equations; as well as categorization according to gender and race. Statistical analysis was conducted using IBM SPSS Statistics Version 21.0. Significant correlations were identified between gender and height estimation measurements, with males being anatomically larger than females (P<0·001). Significant differences were documented when study participants were stratified according to race and gender (P<0·001). Anatomical similarities were noted between Indians and Black Africans, whereas Caucasians were anatomically different from the other race groups. Arm-associated height estimation methods were able to estimate true height; however, each method was specific to each gender and race group.ConclusionsHeight can be calculated by using arm-associated measurements. Although universal equations for estimating true height exist, for the enhancement of accuracy, the use of equations that are race-, gender- and population-specific should be considered.

“…There is no consensus on the most suitable method of height measurement in the critically ill. The gold standard is standing height, which is often impossible to obtain [ 22 ]. Supine height, the most common alternative, may also be prone to various errors.…”

Background Height measurement is crucial for calculating predicted body weight (PBW) and establishing low tidal volume ventilation (LTVV). However, standing height is usually unavailable in critically ill patients and supine height may be difficult to obtain. Objective We investigated whether there were any significant differences in tidal volumes (VT) obtained using PBW derived from supine, forearm, and lower leg lengths in an intensive care unit (ICU) setting. Methods Supine, forearm and lower leg lengths were measured in 100 mechanically ventilated patients. Limb lengths were converted to height and PBW calculated using published formulae. The 6 mL/kg VT for the supine (sVT), forearm (fVT), and lower leg (lVT) methods were compared to each other and to visually estimated VT (estVT). Results Forearm length produced the greatest height estimate, leading to a significantly greater tidal volume fVT (437.6 ± 62.1 mL) compared with sVT (385.5 ± 63.8 mL) and lVT (369.1 ± 66.4 mL), (p < .001). There was no significant difference between lVT and sVT, (p = .169). On Bland Altman analysis, the lowest bias was found between lVT and sVT (−16.4 ± 36.0 mL, 95% limits of agreement (LOA) [−86.9, 54.1]), whereas fVT had a bias of 52.1 ± 41.5 mL, 95% LOA [−29.1, 133.4] compared to sVT. The fVT was significantly greater than sVT and lVT in all sexes and ethnic groups (p < .05). Conclusion Lower leg length may be a suitable alternative to supine height to facilitate the application of LTVV in an ICU setting.

“…A altura também é uma medida que se correlaciona com o volume pulmonar e é utilizada para o ajuste de parâmetros ventilatórios de pacientes em ventilação mecânica. Qualquer erro na aferição da altura pode ofertar volumes correntes de ventilação inadequados, com consequente lesão pulmonar ou desenvolvimento de Síndrome do Desconforto Respiratório Agudo (SDRA) (BOJMEHRANI et al 2016 e LAHNER;KASSIER, 2016).…”

O objetivo deste estudo foi comparar o peso e altura aferidos com métodos de estimativa correspondentes em pacientes internados em um hospital da cidade de Juiz de Fora. Estudo transversal realizado no período de maio a dezembro de 2016 com a coleta dos seguintes dados: gênero, idade, raça, motivo da internação, peso, altura, altura do joelho, circunferência do braço, abdominal e da panturrilha, comprimento do braço e da ulna, semi-envergadura do braço e dobra cutânea subescapular. Foi empregado teste t pareado para comparar os valores de peso e altura aferidos foram com aqueles obtidos a partir de fórmulas de estimativa, considerando nível de significância estatística o valor de p < 0,05. Foram avaliados 90 pacientes, sendo 53,3% mulheres, 67,7% adultos e 68,9% eutróficos. Para a estimativa de peso corporal, as fórmulas de CHUMLEA et al. (1985) e (1994), RABITO et al. (2008) e MARTÍN et al. (2013) não se diferenciaram da medida de peso aferido (p > 0,05). Para a estimativa de altura, as fórmulas que não se diferenciaram foram as de CHUMLEA et al. (1985), CHUMLEA et al. (1994) e SILVEIRA et al. (1994) (p > 0,05). Concluiu-se que as equações de estimativa de peso e altura que utilizaram medidas de circunferências e altura do joelho em suas fórmulas se demonstraram adequadas para a estimativa de peso e altura em adultos e idosos hospitalizados. A escolha do método deverá ser baseada conforme disponibilidade de equipamentos e avaliadores treinados para realização das medidas.
