Re: Vitamin D insufficiency even in sunny southern Arizona

[Guest guest]

Nobody who lives in southern Arizona is outside when the sun is burning.

I believe that the Arizona state bird is the Air Conditioner.

Background: Vitamin D deficiency or insufficiency has been observed

among populations in the northern United States. However, data on

the

prevalence of vitamin D deficiency in areas of high sun exposure,

such

as Arizona, are limited.

Objective: The purpose of this study was to analyze serum

25-hydroxyvitamin D [25(OH)D] concentrations in residents of

southern

Arizona and to evaluate predictors of 25(OH)D in this

population.

Design: Cross-sectional analyses of serum from participants in a

colorectal adenoma prevention study were conducted to determine

rates

of vitamin D deficiency. Participants were categorized into 4 groups

on the basis of serum 25(OH)D concentrations: <10.0 ng/mL,

& #8805;10.0 ng/mL

and <20.0 ng/mL, & #8805;20.0 ng/mL and <30.0 ng/mL, and

& #8805;30.0 ng/mL.

Results: The mean serum 25(OH)D concentration for the total

population

was 26.1 ± 9.1 ng/mL. Of 637 participants, 22.3% had 25(OH)D

concentrations >30 ng/mL, 25.4% had concentrations <20 ng/mL, and

2.0%

had concentrations <10 ng/mL. Blacks (55.5%) and Hispanics

(37.6%)

were more likely to have deficient 25(OH)D concentrations (<20

ng/mL)

than were non-Hispanic whites (22.7%). Sun exposure had a greater

effect on 25(OH)D in whites than in blacks and Hispanics, whereas

BMI

appeared to be more important in the latter groups.

Conclusion: Despite residing in a region with high chronic sun

exposure, adults in southern Arizona are commonly deficient in

vitamin

D deficiency, particularly blacks and Hispanics.

We have been hearing the warnings about skin cancer for many, many

years. The first thing that people do before they go out in the sun

is apply sun block. Women's cosmetics have ultraviolet blockers to

" prevent wrinkles " and " sun damage " . The pigments in women's face

powders and foundation cosmetics also block the sun on the face which

is the only part which will probably be exposed to the sun.

I think that women probably get less sun exposure than men because of

cosmetics.

From my own personal experience and observation, I have to agree

though I think sunblock and all the UV treated clothing and windows,

etc matter also.

I live in in N Miami where we have sunshine all year similar to AZ.

Most all locals I know avoid the sun due to its strength and power.

I know that except for the times I am out purposefully getting sun, I

am covered all the other times. I always wear big funny sunglasses

that go over my reg glasses, a hat, and always have on a light cotton

long sleeved shirts and pants.

There is a joke down here that you can tell the difference between the

tourists and the residents. The tourists are in bathing suits and/or

shorts while the residents are clothed and covered up. It really

stands out in winter. though the sun is strong, and it is warm, we

all think of 70 as freezing, so the tourists are in bathing suits and

the residents are in down jackets.

Most women (if they are like me) only use sunblock on their face. I don’t use it on my legs or arms which are exposed in the summer to the sun. I insist my husband (who is very fair – a redhead in his youth) use it on his face (only) in the summer. The face gets more all-year-round exposure than any other part of the body.

A larger factor I would think would be not being outside in the sun. Summer clothing (shorts, short sleeved tops) would allow plenty of skin to be exposed if one is outside. But if people have indoor jobs all week long, and lack of exposure on weekends (too hot, too many things to watch on tv etc), that would lead to a deficiency.
