Description Usage Arguments Details Examples

Get an estimate of ideal body weight. This function allows several commonly used equations

1 2 |

`weight` |
weight in kg, can be vector |

`height` |
height in cm, can be vector |

`age` |
age in years, can be vector |

`sex` |
either 'male' or 'female', can be vector |

`method_children` |
method to use for children >1 and <18 years. Choose from 'standard', 'mclaren' (McLaren DS, Read WWC. Lancet. 1972;2:146-148.), 'moore' (Moore DJ et al. Nutr Res. 1985;5:797-799), 'bmi' (), 'ada' (American Dietary Association) |

`method_adults` |
method to use for >=18 years. Choose from 'devine' (default, Devine BJ. Drug Intell Clin Pharm. 1974;8:650-655). |

`digits` |
number of decimals (can be NULL to for no rounding) |

Equations:

<1yo Use actual body weight

1-17 years old ('standard'): if height < 5ft: IBW= (height in cm2 x 1.65)/1000 if height > 5ft: IBW (male) = 39 + (2.27 x height in inches over 5 feet) IBW (female) = 42.2 + (2.27 x height in inches over 5 feet)

Methods not implemented yet: McLaren: IBW = - step1: x = 50th percentile height for given age - step2: IBW = 50th percentile weight for x on weight-for-height scale Moore: IBW = weight at percentile x for given age, where x is percentile of height for given age BMI: IBW = 50th percentile of BMI for given age x (height in m)^2 ADA: IBW = 50th percentile of WT for given age

>= 18 years old (Devine equation) IBW (male) = 50 + (2.3 x height in inches over 5 feet) IBW (female) = 45.5 + (2.3 x height in inches over 5 feet)
