Ecological studies—which investigate the relationship between geographical variation in disease outcomes and the risk-modifying factors for each geographical unit of population or seasonal variation—can be useful in identifying and quantifying relationships between solar UV-B doses and disease outcome. The ecological approach has linked low solar UV-B doses to about 20 types of cancer.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> The time-varying ecological study approach has linked solar UV-B to reduced risk of influenza.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">Observational studies can be either case–control studies, which measure serum 25-hydroxyvitamin D [25(OH)D] concentrations at time of diagnosis, or nested case–control studies derived from cohort studies. Cohort studies compare patients who have the disease with similar healthy controls, grouping the disease by quantiles of 25(OH)D concentration. Case–control studies find stronger inverse correlations between 25(OH)D concentration and disease incidence because nested case–control studies measure vitamin D status with a single serum 25(OH)D concentration at time of enrollment; over time, this sole measure becomes less reliable.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a></p><p id="par0020" class="elsevierStylePara elsevierViewall">Cross-sectional studies are snapshots of health conditions and biometric values made by random sampling of the population.</p><p id="par0025" class="elsevierStylePara elsevierViewall">In randomized controlled trials (RCTs), some participants receive the agent and others a placebo. Participants are followed up for weeks to years, and health outcomes, both positive and negative, are noted. Using RCTs to study the effects of vitamin D on disease outcome poses many problems: the dose is often inadequate, compliance may be poor, other sources of vitamin D exist, and serum 25(OH)D response to oral vitamin D intake varies considerably from person to person.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a></p><span id="sec0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Vitamin D requirements</span><p id="par0030" class="elsevierStylePara elsevierViewall">With this background, we can now address how vitamin D requirements can and should be determined. Relationships between serum 25(OH)D concentration and disease outcome are essential. Ecological studies provide indirect information because they use indices of solar UV-B dose. RCTs generally use a single dose and so have difficulty representing the entire relationship unless several such studies are included in a meta-analysis or in a pooled analysis. That leaves observational studies, which use serum 25(OH)D concentrations and generally provide 4–5 values for serum 25(OH)D concentration to use in determining relative risk (RR), hazard ratio or odds ratio (OR). Because single observational studies have large uncertainties, several observational studies should be combined in either a pooled analysis or a meta-analysis.</p><p id="par0035" class="elsevierStylePara elsevierViewall">In an earlier work, I recently combined observational studies of breast and colorectal cancer incidence with respect to serum 25(OH)D concentration in meta-analyses.<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">6</span></a> Values from various studies were combined by overlaying the values such that the center of the regression fit to each study overlapped.
