Summary
Breast size differences are linked to body mass and BMI. Body mass index and suprasternal notch to nipple distance can predict breast mass, challenging current mammaplasty criteria.
Area of Science:
- Anthropometry
- Body Composition
- Plastic Surgery
Background:
- Current mammaplasty selection criteria often rely on weight-related factors.
- Weight loss is frequently recommended for breast size reduction.
- The relationship between breast size and overall body composition is not well-established.
Purpose of the Study:
- To investigate anthropometric differences between women with smaller and larger breasts.
- To identify predictors of breast mass.
- To evaluate the suitability of current weight-related criteria for mammaplasty.
Main Methods:
- 93 women (A to H cup sizes) had bra band/cup size determined by a fitter.
- Breast mass was estimated (categorized as <500g or >500g).
- Anthropometric measurements included body mass, BMI, skinfolds, body fat percentage, and suprasternal notch to nipple distance.
Main Results:
- Larger breasted women had significantly greater body mass, BMI, and suprasternal notch to nipple distance.
- Body mass and suprasternal notch to nipple distance were positively correlated with breast mass.
- Body mass index (BMI) and suprasternal notch to nipple distance explained 50% of the variance in breast mass.
Conclusions:
- Significant anthropometric differences exist between smaller and larger breasted women.
- Body mass and BMI are strongly related to breast mass.
- BMI and suprasternal notch to nipple distance can predict breast mass, suggesting weight-based criteria for mammaplasty may be inappropriate.

01:12The Mammary Glands
The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

01:12Coefficient of Correlation
The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable x and the dependent variable y.
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the strength of the linear...

01:10Nature and Nurture
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
01:18Polygenic Traits
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
02:12Relationship Formation
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

One-way ANOVA can be performed on three or more samples of unequal sizes. However, calculations get complicated when sample sizes are not always the same. So, while performing ANOVA with unequal samples size, the following equation is used:
